Sparrow, Lewisham

Lentil vada, coconut chutney
On Sunday night we went to Sparrow in Lewisham for Becks' birthday. We've wanted to go since they opened but morning sickness and a baby had got in the way until now.

The menu is an eclectic mix of Italian, Indian and south east Asian influences with some French and north African flavours sprinkled in to. It sounds like it could be a car crash. Can one kitchen really pull off all those different flaovurs in a cohesive way? I'm pleased to say, as it was a birthday dinner, yes they can.
Burrata, slow cooked courgettes
It was difficult to pick a favourite from the mains. The green risotto still had incredible bite but there was no hint of chalkiness and the pine nuts sprinkled on top had been toasted deeply adding a great flavour. How did they manage to toast them that darkly without burning them?

The vada, burrata and lamb were all dishes I'd order again too. Already being full we shouldn't have ordered dessert but did the lure of sugar drew us in. They didn't feel up to the level of the main courses but it's a bit unfair to judge them when we were so full.

It took us a long time to get to Sparrow, but hopefully we'll organiser another babysitter and be back sooner next time.

Raleigh Strada eBike review *Updated*

I bought my eBike three weeks ago to use on my daily commute into the office. My previous bike was ten years old, and although the frame was probably the only original component still left on the bike, I'd been scratching the itch for something new for a couple of years.

A more immediate driver for buying the bike was my 10 month old daughter. She's a bundle of joy but has definitely meant I get a lot less sleep than I used to and cycling home after a day at work on little sleep was becoming increasingly difficult. Some days I was getting the train to work as I knew I wouldn't be able to manage the ride home.

eBikes are becoming increasingly common in bike shops in London, but most places only carry a very limited range. I knew that I wanted a crank drive, but was really pushing my limited budget to get one. In my budget were a very limited number of models from Cube and Raleigh. I ended up with the Raleigh Strada largely because the Cube sales rep didn't get back to my local bike shop. Sometimes it is best to leave things to fate...

So what is it like to ride?

Riding downhill: Assistance from the motor cuts out at 25kph / 15mph which is easily exceeded on even moderate inclines. Basically riding downhill is exactly the same as on any other bike. You might get a bit of extra momentum from the bike being heavier than a standard bike, but this isn't something I've tried to measure.

Starting and stopping: Pulling away is one of the two times when I really notice that I'm on an eBike. It takes very little effort to get going and you accelerate away from the lights up to 15 mph very quickly. Given that stopping and starting can be a real energy sapper this is where having some assistance makes a real difference.

Stopping on an eBike is no different to a regular bike.

Riding uphill: This is the second area where riding on an eBike makes a real difference. On my commute I only face a few undulations, but the four small climbs at the end of my ride home were a real struggle on days when I'd had insufficient sleep. The motor makes a noticeable difference and it almost feels like you are riding on the flat which is amazing.

Riding on the flat: Riding on the flat is the thing that has taken the most getting used to which is not something I was expecting. The motor assistance means that you accelerate up to 25 kph / 15 mph and it is actually quite hard to cycle slower than this.

Going quicker: The Strada is a very easy rolling bike so it is perfectly possible to cycle faster than 25 kph / 15 mph under your own power and I frequently do on my way to work. However, I'm conscious of the fact I'm shifting a heavy bike (due to the motor and battery) and it is harder work than it was on my old bike.

Cycling at 25 kph / 15 mph: I find myself cycling at this speed quite a lot due to the electric assistance getting you up to this speed without much effort. The power delivery is incredibly smooth, but I am conscious of the motor kicking in for a couple of pedal strokes, cutting out and then back in again. I'm guessing this must be a pretty common scenario and I'm hoping that it isn't bad for the motor. As I said the power delivery is very smooth and there is no jerkiness.

When you see people on eBikes zipping past you on the flat you realise how many must have had the limiters removed / don't comply to UK law.

Range anxiety / Battery life: Quite simply I don't have any range anxiety. I've been charging the battery once a fortnight after covering 80 - 90 miles (at around 15% battery left). Battery charging is quicker than I expected too, taking 2-3 hours.

Power Modes: The Shimano system has three power modes, Eco, Normal and High. I only really ride in Eco as it really provides a significant boost and on a mainly flat commute like mine that is all you need.

If I'm feeling really lazy on the final drag home I might turn the bike to Normal and then you barely do have to pedal.

Noise: Something I hadn't expected, but is pretty obvious if I'd thought about it. I'm not saying the motor is noisy, in fact it's pretty quiet, but you can't escape the fact it does make a noise. In traffic you won't hear it, but on a quiet country cycle path or country lane you are likely to hear it. More importantly so will the people you cycle past, and they'll know you are cheating.

Quirks: The only quirk I've noticed is that you can't turn the system on while pedalling, so you need to turn it on before you jump on the bike or while you are rolling, but not pedalling. I think this is because there is a torque meter in the motor and it needs to calibrate each time you start cycling.

Overall I'm really happy with the bike. It's fun to ride and on the sleep starved nights it still makes me want to cycle to work, which was the whole point of buying the bike. The only downside I can see is that more and more manufacturers are integrating the battery into the bottom tube so I think the bike is going to look pretty dated in a couple of years with the battery so visible on the frame. It might also make me fat as I'm exercising less than on my old bike.

A quick hat tip to my local bike shop Parts and Labour who gave me some good advice before the purchase, sourced the bike at a great price and have given me good service since then. I have no affiliation other than being a happy customer.

I've had the bike for around 5 months now and use it most weekdays. Overall I'm still very happy with the bike and continue to enjoy riding it.

However, I thought I'd share a minor annoyance with the battery. In a nutshell the amount of battery remaining doesn't go down in a linear fashion. I've had a few instances when the amount of battery left suddenly drops by 20%, I've also seen some 10% and 15% drops. This seems to happen when I've got less than 40% of the battery left.

I still only need to charge the bike around once a fortnight so I don't think the battery is failing or the capacity has noticeably reduced. It seems to be more of a battery management issue which means I never quite trust how much battery is actually left. As my lights run off the main battery I really don't want to be caught with no power left and a ride home in the dark.

Domestic energy monitoring: Is a home battery worth it?

Cross posting a Twitter series I've started onto the blog.

I love the idea of a home battery to connect to our PV system because I'm a sucker for new technology, even if I know they won't be economic until about 2030. As a way of delaying the purchase by a minimum of 12 months I've decided to collect a year of data 1/

The measurements are complicated by a) getting good data, b) because we already store some electricity in the form of hot water via our power diverter and c) because I don't know what I'm doing. C is without doubt the biggest problem. 2/

I'm going to ignore peak loads, that can be my reason for putting off a purchase in year two 3/

June 2018: Average import of 3.5 kWh per day, stored 4.9 kWh as hot water and exported / could have stored 6 kWh in a battery. Max import on any day 5.3 kWh. Conclusion: A battery could have made us off grid. 4/

July 2018: Average import of 3.6 kWh per day, stored 4.6 kWh as hot water and exported / could have stored 5.8 kWh in a battery. Max import on any day 5.6 kWh. Conclusion: A battery could have made us off grid. 5/

August 2018: Average import of 4.2 kWh per day, stored 4.1 kWh as hot water and exported / could have stored 2.9 kWh in a battery. Max import on any day 6.5 kWh. Conclusion: A battery could have met 70% of our needs. Could have been off grid if we stored less as hot water. 6/

September 2018: Average import of 4.2 kWh per day, stored 3.9 kWh as hot water and exported / could have stored 2.3 kWh in a battery. Max import on any day 6.5 kWh. Conclusion: A battery could have met 50% of our needs. Could have been off grid if we stored less as hot water. 7/

Classic sunny, but short, autumnal day. Completely mismatched generation and demand for a working family. Exported 4.4kWh and imported 5.5kWh (so far). 8/

October 2018: Average import of 6.2 kWh per day, stored 2.3 kWh as hot water and exported / could have stored 1.0 kWh in a battery. Max import on any day 10.9 kWh. Conclusion: A battery could have met 20% of our needs or 50% if we didn't store any electricity as hot water. 9/

Generation continued falling in October and our electricity consumption rose significantly making it a bad month for energy independence! We have a number of electric heating sources that we use as a little top up before the central heating comes on. 10/

November 2018: Average import of 7.6 kWh per day, stored 0.9 kWh as hot water and exported / could have stored 0.3 kWh in a battery. Max import on any day 9.7 kWh. Conclusion: A battery could have met 4% of our needs or 20% if we didn't store any electricity as hot water. 11/

The stats this month are looking pretty bad, but if we had some form of local / district storage we could still be energy independent for about another month based on all the excess generation over the summer.

December 2018: Average import of 7.5 kWh per day, stored 0.1 kWh as hot water and exported / could have stored 0.4 kWh in a battery. Max import on any day 10.6 kWh. Conclusion: A battery could have met 5.6% of our needs or 6.5% if we didn't store any electricity as hot water. 13/

The December stats look pretty bad again, but if we had enough storage we could still be energy independent based on our summer generation. This is the last month I'm likely to be able to say that though. 14/

In 2018 we earned £453 from our solar panels in generation and export tariffs 15/

January 2018: Average import of 8.3 kWh per day, stored 0.0 kWh as hot water and exported / could have stored 1.0 kWh in a battery. Max import on any day 11.4 kWh. Conclusion: A battery could have met 12.4% of our needs 16/

February 2018: Average import of 6.8 kWh per day, stored 0.0 kWh as hot water and exported / could have stored 3.3 kWh in a battery. Max import on any day 10.3 kWh. Conclusion: A battery could have met 48% of our needs 17/

The Big Half: Build Up and Race Notes

Herbert and my Big Half Medal
Prior to competing in the Berlin marathon back in 2015, running had been a big part of my life for four / five years. I've been running reasonably regularly since then, but nowhere near the same level of intensity. At one time a 50 mile week would be easy and now it feels like something that is unachievable!

I was happy to reprioritise other things in my life (house building, work & family), but at the same time I used to get a bit upset and how far my times had tumbled. Last year when I saw the Big Half announced I decided that it was finally to set myself a goal and get a race in the diary.

Even with a goal in mind, I still let my training drift as the race was a long way off, until the start of this year when suddenly it wasn't any more! At the start of January I put together an eight week training plan together for myself and have actually enjoyed the structure. I could no longer skip a run because "I was feeling a bit tired" or "I didn't fancy running in the rain".

I knew I had to be realistic and that getting close to a PB wasn't going to be remotely possible as eight weeks wasn't long enough to build a base, some speed endurance and taper. Racing the Hagley Park Run while I was in NZ gave me a confidence booster that I should be able to achieve something in the 82 - 84 minute range.

I started race day nice and relaxed. Bumping into fellow club mate John on the start line we decided to run together as we were targeting for approximately the same time.

0 - 5km
We settled into a nice pace pretty quickly (which surprised me as I hadn't done any training at target pace), and despite quite a bit of weaving round slower runners settled into a rhythm. I could feel my breakfast sitting in my stomach. I'd eaten three hours before the race, but that obviously hadn't been enough time to digest it fully.

Around 4km I was beginning to feel that it was a bit quick and started thinking I was going to have to tell John I needed to back it off a bit as I didn't think I'd be able to make it to the end at the current pace. However, around the 5km mark I started to feel ok again.

6 - 10km
Somewhere around the 6km I started to pull away from John slightly and found myself with a group of runners I recognised from the Assembly League, including a very good female runner called Claire. I ran with them for a bit and then started to ease away from them. I knew I was probably going a bit quick, but I was feeling good at that stage so decided to stick with it.

During this phase of the race I also passed a couple of other Kent runners, Matt and Rowan, who would usually beat me. I probably should rain this in.

11 - 15km
I don't remember much about this phase of the race. Somewhere around the 13km marker Claire came onto my shoulder, but then dropped back again.

I was trying not to be too negative, but at this stage of the race I could tell my lack of speed endurance / general training was going to catch up with me and I'd struggle to maintain this pace to the end.

16km - Finish
As predicted I detonated in this phase of the race. I was trying to keep myself positive and tell myself that it was only a Parkrun distance to go (even though it was further) and also not to look at my watch. In the past, even though it has felt like I've slowed to a crawl, my watch has told me it isn't nearly that bad. If I didn't look I could tell myself I'd barely slowed!

I started to feel a blister on my right heel. Do I stop to adjust my sock? No.

At 18km I received a huge cheer from club mate Alison. It was brilliant, even if I didn't feel as good as I was told I looked. It was at this stage that I started going backwards in the race and I was definitely the one being overtaken. I could also hear lots of "go Claire!". I didn't look round, but I knew she must be close.

Keep going, it's not far.

In the final 200m John came onto my shoulder, he'd clearly run a lot more even race than I had and had now caught up with my. I put in a sprint finish and managed to beat John by around 5m.

I finished in 1:23:17. I was 396th out of 11,598.

The data from my watch is here.

The official results are here. With some fun visualisations of the data here.

Super Thai food: Supawan, Kings Cross

I recently read Marina O’Loughlin's review of Supawan, and like many other people I suspect, decided I'd like to try their Thai food for myself. A catch up with my friend Ed last night provided the perfect opportunity.

Marina was universal in her delight at Supawan. We had two awesome dishes and two a bit more average, although the highs definitely outweighed the lows.

First, the highs. The neua yang (grilled beef) is described on the menu as coming with a grounded rice and mint dressing. What they didn't mention on the menu was the amazing sauce that had us both spooning it over our rice to make sure we ate every last drop.

The second excellent dish was the Thai squid (pictured). At first glance it looks like any other deep fried calamari, but the chili and tamarind coating took this squid to a whole different level. I could have very easily eaten another plateful.

The two dishes that slightly missed the mark were two staples that I love ordering on my visits to Thailand. The first was som dtum (papaya salad). In Thailand this salad is ferociously hot and it is a dish that just doesn't work without chili and our just didn't have enough. Phakbung fai deng (stir fried morning glory) universally comes in tasty garlicky sauce, but this one was just a little bland and without enough punch in the sauce.

The beef and the squid were definitely enough to make me want to go back. Hopefully I find some more highs from the menu. At £25 a head it was excellent value and our lovely server even tolerated my poor Thai.

Oh, and I'm pretty sure the bathroom tiles are the same ones as we have in our bathroom too.

Summer in Scotland: Adfern and surrounding area

Neolithic burial mound in Kilmartin Glen
For the final few days of our time in Scotland last summer we stayed at a B&B in the small community of Ardfern with a rather eccentric host (who has since sold the B&B). Here are some of the highlights of our time exploring the local area.

One of the first and most memorable things we did was a guided walk of the neolithic (mainly burial) sites in Kilmartin Glen. The guided walk started and ended at the Kilmartin Museum and we spent a couple of hours being guided round the glen by some very friendly locals. The glen is packed with incredibly well preserved neolithic remains.

I can't remember many fact from the walk now, but I do remember enjoying it at the time. They take a limited number of people on the walks and regularly hit capacity so it is worth getting your name onto the sign up sheet early in the morning and then coming back for the walk in the afternoon.

Not to far from Kilmartin is the small settlement of Crinan. We visited twice, once during the day to go for a walk along the canal and then we returned in the evening for dinner in the seafood bar at the Crinan hotel which is well known locally as one of the best spots in the area for seafood. Having ticked langoustine off my list in Islay, this time I ordered a plate of scallops which was another item on my holiday check list.

Knapdale Forest
Taking advantage of the long summer days up in Scotland we stopped for a walk in the Knapdale forest on the way home from Crinan. The forest is the site of trial to introduce beaver colonies back into the wild in Scotland. We didn't spot any of the beavers, but did see some of their dams and had a pleasant walk round the forest on some of the trials.
At Arduaine gardens
On another long day out and about we started of by looking round the Arduiane gardens (lovely, but we were a bit out of season) before heading up to Oban. Compared to the rest of our trip Oban was tourist central with lots of overseas visitors around. Oban is clearly a tourist hub and a gateway to some of the outer islands.
Lobster in Oban
We had lunch at Eeusk (lobster, the final tick on my seafood wish list)  on the waterfront and a quick look round the centre of town before jumping into the car again and heading to Easdale island, a delightful, if slightly odd experience. 

Wheelbarrows Easdale
The tiny island of Easdale can only be accessed by a small ferry which only takes foot passengers. When you arrive on the island, the first thing you see if an assortment of wheelbarrows that the locals use to transport their shopping from the ferry back to their houses.

The island is covered in abandoned slate mines and was clearly a hub in the activity in its day. The only thing to do on the island is to have a walk around some of the abandoned mines and through the small settlement near the ferry.
Abandoned slate mines on Easdale
The island was very idyllic but it must be a tough live living on the island, exposed to the weather and only able to access your home via a small very. I suspect everyone that lives there must do it because they love the island.

Summer in Scotland: The Isle of Jura

Becks looking towards Lagg
My favourite day of the holiday was the one we spent on Jura, which is just a short hop on the ferry from Islay. It would be fair to say that there isn't much to do on the island apart from drink in the scenery, but oh what scenery it is.

There is only one main road on the island and we spent the day driving as far north as we could (the top of the island is private land), before turning round and retracing our steps in time for a ferry back to Islay.
Inverlussa Bay
The furthest north we went was to the inlet of Inverlussa. In between the rain showers we managed to go for a walk on the beach and a visit to a converted horse box, which is now a make shift café. One of the locals puts a freshly baked cake into the horse box each morning along with a couple of Thermos flasks of hot water. You can make yourself a drink and enjoy a slice of cake and leave some money in the honesty box when you are done.
Tea on the beach
We were thinking about taking on part of Evan's walk, but the wind was howling a bit too much for us. Plus it looked quite a lot like rain....
Evans Walk
No visit to Jura would be complete without popping into the distillery. We'd missed the daily tour, but one of the people working in the shop kindly took us into the distillery to see the stills and also to the barrel room. Once back in the shop I asked if I could do a tasting and much to my surprise they don't do paid tastings but they were very happy to give me a free dram instead!
