climbs are what i ride for. reminds me of andy hampsten saying he could not get excited about a bike unless it had climbing gears (a compact for him). i'm not great at it, and am not even built for it, but i get the most enjoyment out of it. it is the best way for me to gauge and work on fitness.
take your time with it, don't be afraid to move slow, getting off should be a last resort, and i'm sure most of us have done it (my breakdown was on palomar, actually the first two times i attempted palomar i had to dismount). watch videos of others doing it, and get passionate about it.
keep it up!
i love this clip. 2k to go till the race finnish, try to guess who will have the legs in the end.
