I finally tried out Nokia Sports Tracker. Here's a screenshot of my workout:

Yes, screenshot. Nokia, in their ever loving wisdom, don't have embeds. You can download a version of your "workout" in KML, but you can't embed your route. Update added this suggestion to Get Satisfaction.

This is a really interesting service that works well - it's got a great S60 app for your phone with various different modes, and pretty much updates your location in real time both on a map on your phone, as well as beaming it online.

The one issue is that it absolutely *drained* the battery on my N95. We actually spent 6 hours biking around for the Vancouver Bike the Blossoms event, and it would have been great to have a log of the whole event. I charged the phone the night before, so I have no idea why it got so completely drained. Oh, right, and there are the usual Nokia-can't-really-make-web-apps issues, like the fact that I can't share a link to a map of the Vancouver area, showing that there are a dozen or so people using it in this area.
