I'm very happy with the costant gainz I'm doing with my bike since I started riding in september.
I went on the same road I did struggling a few months ago with many ups and down and I totally ripped them this time, never had to stop or use ridicously low gears while going up. Also my average speeds are getting better and better even if by little every time I go.

I guess the improvement will hit a wall somewere but for now I'm enjoying the moment.
