The limiting factor:

[alpinerabbit]

I've been mountainbiking now and then / commuting daily for 6-8 years, until I got a real job in another town 2 yrs ago. But the race bike is new.

next try: 45km and 350 meters up. I nearly died climbing up. My SO had to push a couple times and my pulse was... don't tell me off.... 193 at one point.

But going home was ok, I slept it off and I only had a sore butt (muscles, not sitting bones) for a day.

Clipping is easier already, sometimes I hit them without looking - and new glasses with decent side view make a lane change a joke - like in the old days. I could hold my legs steady and my hands brake-ready going downhill, still slow but getting more confident.

I am so happy my posture seems to be ok! and thanks for the hint about the crew cut elsewhere.
