on slowing down

John sent a link to our loose group of cycling buddies, and I’ve read the article 3 times now. Each time, it feels like it hits closer to home.

I’ve been riding my bike as the primary way of getting around, and have been communiting by bike almost exclusively since 2006. I’ve always ridden, but never really considered myself a cyclist until then. I was never athletic, never good at sports. But I was happy on a bike. Over the years, I actually got pretty good on a bike. I could make it go fast. I could climb hills. I could ride far. It was awesome.

And then it started feeling less awesome. Most recently, with my bad knee. Late last year, I somehow managed to get a stress fracture at the top of my tibia. I didn’t even know it had happened, and only wound up at the doctor because I thought I was dealing with progressive arthritis or something. Nope.

We couldn’t find any specific incident that might have caused it, but the doctors thought it may have been related to repetitive stress and strain while riding ~5,000km/year. Which meant it was self-inflicted. I’d been pushing myself for the last few years to try to keep up that pace. And, while limping around like a 70-year-old, I realized that I hadn’t been doing myself any favours. One knee is already pretty much shot, the other is likely not far behind it. And pushing to hit 5,000km/year wasn’t helping things. I’m largely recovered now – the knee is still sore, and feels weaker than it should, but it works. Physio has helped, but it’s obvious I need to pay attention to it before it gets worse.

I’ve been tracking personal metrics since 2006 – with detailed GPS logs since 2010, thanks to my use of Cyclemeter. Recently, I’ve added Strava to the mix. I really notice that I push myself more when I know a ride will be posted to Strava – either I need to let go of that, or I need to stop posting rides1.

I’m not really sure why I was pushing myself to keep hitting 5,000km/year. I think it was the feeling of accomplishment, of achieving a goal that not many people do. Some kind of macho “I’m not getting old! look what I can do!” thing. Whatever. I’m letting that go. I’m still going to ride as much as I can, but I’m not going to push it. I’m going to slow down, again. And have fun.

I’m registered in the Banff Gran Fondo this weekend. 155km, from Banff to Lake Louise and back2. I had been stressing out, because I lost 6 months of riding – of TRAINING! – and there was no way I’d be able to keep up a competitive pace. But that’s OK. I’m going to go for a nice ride. Stop at the rest stops. Enjoy the mountains. And I’ll finish when I finish.

  1. but ride data from Strava is now being used to inform policy and decisions about cycling infrastructure and civic planning, so I think I need to keep posting it for now… []
  2. depending on how well the local bear population cooperates []

2013 Tour of Alberta

Evan and I headed downtown for the finish of Stage 5 of the Tour of Alberta (along with several thousand others). What an amazing event, and a fantastic finish. Hopefully this isn’t just a one-off – it would be incredible to see it come back next year, with some mountain stages (the 1 mountain stage that had been planned was rerouted because of the June flooding in Alberta – hopefully next year’s route would include a stage over Highwood Pass and maybe through the Rockies).

I took a boatload of photos, and we had a blast. Now Evan wants a new bike…

fun with bike data visualization

I just picked up a license for the fantastic OmniGraphSketcher application. I’m using it to build the visualizations for my thesis, and wanted to see what it would do with my bike tracking data. OK. I was procrastinating, and couldn’t force myself to work on the thesis. But, at least I’m learning how to do more cool stuff with data, right? cough

Anyway. Here’s a visualization of almost 2 and a half years of data stored in Cyclemeter on my iPhone. I exported the activity history in monthly aggregate, and took the .csv file into Excel to select the rows, which were then pasted into OmniGraphSketcher. The visualization shows total distance (divided by 10, so the distance data points fit in the same range as speed data), average speed and maximum speed per month. I also overlaid lines to show which bike was being used. The Kona wound up being my winter bike, and my Cannondale is my fast summer bike. It’s pretty easy to see where the snow and ice crapped up my rides 🙂

compare the OmniGraphSketcher graphic above, with one I created directly in Excel back in July:
