Damn!

Just found out that because of the revised route (couldn't go over Tower Bridge because of the bridge bit being up and therefore danger of 2,000 people in red t-shirts falling off and drowning), it was only 3 miles last night and not 3.5 miles so I'm not as finely tuned an athlete as I thought. Bugger!!

Oh well, I still loved it so that's the main thing.  I suppose.
