I have put on a couple of Kg recently I am now 70kg was 68kg for a long time, but I seem to be getting better results.
I had a decent ride (for me) earlier this week on Braek-Fast Grits and Crits, the short punchy hills are my kind of hills
I stayed with the front group over the first hill but got dropped on the second rise, I dropped in with another group who I stayed with until halfway round the four small hills, on the final climb I caught someone 28secs in front, passed him just before the finish and took no notice of how he was doing, he outsprinted my for the line, 15th in race 12th on ZP a 4 point increase in ZRC, 3.3 w/kg which is at the top end of my efforts.
