Personally I can not spin RPMs of over 100 for extended period of time, expecially with 180 mm cranks all though I can spin up to 120 at times. I tend to mash when I try and close gaps which is why I probably get tired when in the pack, always trying to close gaps.

Someone said that I need to stay out of the big gears for a long time and try and conserve energy. It seems like they mean spin vs mash. The inability to spin at over 100 RPMs for a long time may have to do with the need to work on areobic base more in the off season which I will look into.

Thanks again...
