One of the things that has sparked my interest of late has been the iphone app Strava. I've been using Cyclemeter for the last 18 months or so and I'm very happy with it. The app is reliable and does more things than most people would ever want from an app. My favourite feature is the app talking to you at pre-set intervals, informing you how you're doing. It's quite a nice addition to the top pocket of the handlebar bag.
Strava takes a different approach. The app itself offers a similar, if simplified interface for logging rides, but it's online that it really comes into its own. Think of it a social networking for cyclists. Apart from "competing" with your own times, Strava logs the times of every other cyclist who rides sections of road nominated by users as "segments". These are usually hill climb. The app then ranks you against other riders automatically, producing a league table for the segment. So for any given ride, the app or website may inform you that you've done a personal best, or even ridden such and such a segment faster than anyone before.
I'm a pretty slow rider so there's no King of the Mountains results for me in there, although it is quite amusing to know that on my meanderings I'm recording the slowest or second slowest times for sections near and far.
Strava offers a little applet for your blog, which is handy, although mine displays miles not kilometres despite the opposite being my preference and doesn't seem to update correctly. These little niggles are perhaps outweighed by the fun of seeing just how many speedy cyclists there are out there to 'ride against'. The free Strava app is well worth a look. I'll see how Strava develops before laying out for the Pro version, which estimates watts and gives a 'suffer score' - whatever that may mean.
1607km so far this year.
