So 2015 is my first year cycling, I started in may or so to try to lose weight, I've done ~1100 miles since then. When I first started I was on a 38lb Wal-Mart mountain bike (size 24"wheels) and I was able to do about one mile until my knee's started killing me. Today while I was eating Christmas candy I decided to go try a climb that I haven't done in a month or two and record it to track progress. As I was going up I kept checking off places that I had stopped for breaks the last time I went up, after I got to the top I compared my two strava efforts for the climb and noticed in 2 months I had knocked off almost 10 minutes on my time for the hill, and this time I had a headwind the entire way. 3.8 miles 1112ft of elevation gain 7.8% avg gradiant 8.0mph average. in this year alone I went from covering 1 mile max on flats to doing 60-70 mile rides and climbing 4 miles of hill. Can't wait to see what the 2016 season has in store for me.

Has anyone else noticed any extreme changes in their ability in the 2015 season?
