When I got my bike in May, I was having a tough time doing 12-16 miles in a week. Last week, I did 30 miles. I've gone from having a tough time maintaining a decent cadence of 60-80 rpm, to it's doable. I've gone from barely being able to keep going on the second chainring to mostly riding on the biggest one... including some hill climbs. I did an 8 mile ride, the longest ride I've ever done.

My nemesis hill is still taunting me. I made it up further than I have before by about 15 feet.

I'm boggled at the change in my fitness level.
