Today, my dad and I went out on a short but intense ride- he was on his 20 speed and I was on my newly converted single speed commuter. HOLY CRAP! Going 25mph was a complete pain in the ass, I had to accelerate as fast as I could, then coast until I needed to get going again.

Uphill was another story- it seemed that since I was forced to keep a lower cadence, I was going much faster than usual.

Hills are my new best friend.
