It builds character.

And guads.

I left work about 30 minutes later than normal this afternoon, and the MUP was swarming with cyclists. I passed quite a few. Saw several going the other way. I think somebody was trying to catch me but never got close. My chain is starting to skip under load. Time for a drivetrain overhaul I fear.

Oh and I noticed my bike hit 4,000 miles on the ride home. Sweet.
