i am 46. soon to be 47. i sleep 5 consecutive hours every night. when i hit that 5 hour mark, i wake up feeling alert and ready to rock. if i went to bed at 10, then it really sucks. i have no idea where this came from. when i was a teenager, i would sleep thru multiple alarms, racking up 10 or 12 hours of sleep. but whatever, life is what it is.
performance-wise, i like to work out when i wake up. that means a lot of runs or trainer time at 0430 or 0500. and i do ok, for me, a consistent MOPer. BUT, every once in a while, i get to work out in the early afternoon. daylight, fresh air, fully caffinated ... :-). those workouts are much better. more power, more speed, etc. so, get the sleep you can get. schedule your workouts appropriately.
