Uh, strava.com?

I'm a big fan of Strava, but it's not very useful when it comes to doing stuff with power data. Their premium accounts have some basic analytical tools, but I can't imagine any power meter using cyclists using that as their primary analytical app.

One of the first things I made my site do was upload rides to Strava, because I was tired of having to upload my rides to multiple apps.

This looks good. So many people are sick of WKO and Training Peaks.

Have you checked out Golden Cheetah? It's got most of what you have, plus it can control computrainers, etc. It's a great cross platform desktop app, but the UI needs some loving.

Thanks. I like Golden Cheetah, but I had a few itches I wanted to scratch... Amongst other things, having it as a webapp lets me use this on all of my computers.

Looks very nice (Golden Cheetah user with Garmin Edge 705 and PowerTap SL+ hub).

What about tools to help edit out unwanted sections of a recorded ride?

My type of riding, mainly long distance (Audax), means rides of 9 hours or more (up to 116 hours) with various length stops for food and/or naps (for the multi-day rides). It was a lot of faff with Golden Cheetah (or even editing the .tcx files directly) to trim out sections where I'd stopped and accidentally left the Garmin recording.

Some nice way of selecting a chunk of a ride (whilst either looking at a zoomed in map or selecting a section in the speed/power/cadence/HR graph) and then moving it to a new 'lap' (where it could be kept or deleted) would be very useful.

Cropping rides is something I'll be adding soon, but I hadn't thought about removing sections. Actually, at the moment, I'm essentially treating rides as arrays of records at one second intervals, so having gaps in the middle doesn't work. To be honest, I hadn't considered the use case where you have a single ride file that legitimately spans multiple days. I'll think about this.

Thanks, that probably explains the behaviour I'd emailed you about. Niche use case though, there aren't that many of us long distance loonies out there (The Great Southern Randonee 1200km late October starts quite close to you: http://www.gsr1200.com.au/gsr1200/Home.html ).

Let me know if you need some example large data files to test scalability. I've got one .tcx file (with heart rate, cadence and power data) that's 41MB (would have been 53MB if I hadn't had to reset the GPS part way through).
