Combining GPX files for Strava

This morning was spent on my bike… as was a fair chunk of this afternoon… as is a fair chunk of many summer weekends, much to Mrs W’s disappointment.

My friend Andy and I put in 60 miles in the sunshine, on a big loop around Milton Keynes. It seems my route planning is pretty spot on, as it was almost the exact opposite of a charity ride going the other way around (we passed the same riders twice!). Unfortunately, my ability to “press the start button on my Garmin cycle computer” is clearly less good – I was about a mile from home and heading out of town when I realised I’d forgotten to start tracking my ride!

My OCD can’t cope with this. It would be able to cope with turning around, going back up the hill, starting the computer and starting the ride again – but not with some missing kilometres in my ride data! Luckily, Andy was also riding with a Garmin bike computer. Even though he’d also forgotten to start his, he was wearing a Garmin watch too – so I could combine his data and mine (we’d ridden side by side for the first part of the ride…).

I’ve blogged before about GPS Track Editor, which is a fantastic piece of free software. Using this, I could edit Andy’s data to just the part I had missing, then combine it with mine and merge the two tracks (the short gap doesn’t matter – Strava will straight-line the route between the two points). I also tried merging the files with a tool from gotoes.org – unfortunately, that ended up with a ride that was effectively double the length of what we rode (two loops). it would probably have worked with my edited files but I could also merge them in the GPS Track Editor…

I then deleted the original (short) ride from Strava and re-uploaded. Sorted.

Just one thing to sort out – all of the PRs I got on today’s ride (and there were a few) were recorded as second places by the second upload. No worries – Strava has a “refresh my achievements” tool. which sorted out that particular issue. Now my ride has the complete distance… and my achievements are correct too…
