Today's ride with Nerdsgirth/Fuzzz/Shapelike(/Sara):

Apparently it recorded the time we were sitting still having lunch, even though I hit stop on the computer. Weird.
edit: heh.. just clicked the 'speed' section. My fastest speed was 56km/h... going uphill!

That must have been when I was hammering down that one really rolling doubletrack section and trying to get enough momentum to make it up a hill without having to drop down into a granny gear.
