Short, fat and slow...
I don't particularly see myself as any one of these things, but that sure is how I felt yesterday while biking home when a bunch of roadies on the way to the Tuesday night races out at UBC passed me.
One guy must have been 6'4"; at least that's how tall he looked. I could probably have kept up with them for a bit, but their "casual pace" would have been a pretty hard workout for me.
Last I saw, they were calmly cruising up the top of the hill to UBC, about to blow by a frightened mountain biker that was scurrying up infront of them.
