Cycle Computer

Experimented with the Wahoo fitness key this morning, with my Powercal HR strap.

Initially I used the Wahoo Utility to scan and recognise the two sensors that the HR strap presents as - a power meter and a heart rate meter in one.

I then opened the Wahoo Fitness app- which didn't recognise either sensor.

Great.

I then opened Strava, which immediately recognised both sensors (although I don't know if this was the result of the initial pairing in the Wahoo Utility or not, to be fair).

Rode to work, had an argument with a bloke in a van (tricky doing a chicken impersonation whilst track standing), got to work and Strava had neatly logged HR, GPS track, Power and Speed.

Downloaded the GPX and had a look at that- sadly this doesn't include power data (I am guessing you'd need a TCX for that, which they no longer allow you to download?)

So I entered the ride metrics into Training Peaks manually, which gave me a TSS value- the goal here.

A bit of fiddling later and the Wahoo Fitness App had decided that my HR/PWR strap did exist after all, so I'll test that on the way home.

The Wahoo App is configured to automatically upload the ride data to services of your choice, I have Strava and Training Peaks configured, so theoretically once I hit "save" the ride data will go to both of these.

I've been putting commuting miles into Training Peaks with a very broad estimate of TSS so far, and when I'm lazy and do the whole thing at the end of the week I've often forgotten how much effort I was making, so the goal here is to have a much more accurate (although yes, this is a PowerCal) record of what I've actually been doing.

One last thing- running Stava, the Wahoo App and the fitness key all at once chewed through half my iPhone 4's battery in the space of 50 minutes.
