i agree, core strength is needed and i STILL lack it.

i need to go back and see what i wrote above last year, but today, at GRANOGUE (my first of the season), even after doing a decent warm-up, riding the course through at moderate speed, refueling, even biting the head off a gel pack, i STILL didn't have any reserves to simply GO AT IT like i want and need. maybe it's my age. i cramped out the last lap. i admit, i finally switched to clipless and the mud made things harder, but that really wasn't the issue.

i am thinking of doing some anaerobic threshold training. or drinking 5 5 hour Energy bottles...

seriously, tho, i don't know what i can do to store energy in my muscle...what little there is. i'm 47, 5'8", 150 pounds. in great shape. but not during a cx race...

would LOVE to hear some tips on endurance/stamina
