I like this, good way to work out who flew past you at warp speed.

That's brilliant fun, tried it on a few local sportives I knew happened recently (not my cup of tea) and you can see a few shall we say creative routes from riders

That explains how someone tagged themselves into my ride last week. Spooky

If you think about it opens up the possibility of "mates" races in future.
You do an underground event where you all start at the same time, upload the ride, then watch what happened in playback mode.

I predict Strava will be running "events" using this in future, obviously in the USA though.
