It's not hard to eat while bicycling - I just pull over for a moment.

Any other exercise, you just stop doing it for a moment. It's hard to think of sport or exercise that wouldn't let you stop and eat. Maybe long distance open water swimming??

As far as oatmeal - LOL, I don't bring it cooked. I just eat raw instant oatmeal washed down with protein drink. I keep the oatmeal in a little sandwich bag. It's light and fits in pocket. I pull over to eat it - don't want to crash my bike, lol.

I find that drinking whey protein with carbs helps my performance a lot and shortens the recovery period. Eating fat during exercise upsets my stomach.

High intensity weight training. I can't even face eating for quite a while after the workout.

That makes sense - the hardest workout I do is a mountain bike climb up a really steep hill for about 90minutes with frequent breaks. I suppose it's analogous to doing sprints intervals.
I haven't done weight training for a long time, and you're right that it's a different level of exertion. The biking gets me pretty tired and sore but it's nothing like the exhaustion from really hard core weight lifting.

Have you guys looked into the CKD/TKD diets from the hardcore bodybuilding crowd? The carbup day seems pretty dangerous, LOL.
