I'm 6'0 / 205... I can climb OK up to about 40 miles out. After that, I do slow a little on climbs. We have a ride with about 9 miles of steady climb gaining 1500' or so. I can grind along in the low teens. OTOH, we can climb the same ridge from the side gaining the same elevation in 2 miles. I suffer up it in my granny ring at 5 - 6 mph. I'm not the first up hills on group rides but I'm usually there with the main bunch.

I don't have any illusions about being a racer. I'm not and never will be. I am content to be able to hang with brisk group rides that average 17 – 19 mph over 50 miles or so. I’ve resolved to get down to 190 by the end of the year, then 180 by the end of the next year. Hopefully by then, I can get to the top first if I choose. That would be icing on the cake.
