So having been off cycling for a few months I am starting a new job in Feb and will be cycling 20 miles a day (works out at just under 2 hours a day cycling) I also want to do P90X (not the cardio ones though) which probably works out at about 45mins every other day during the week and will do one cardio thing at the weekend with one rest day. Also want to do a martial art one night a week.

Obviously won't be jumping into this right away, will start with cycling and then add the rest slowly.

My question is "is this too much"?

(I am 23 and in good health and am generally fairly fit).

Thanks
Daven
