I did 81 hilly miles yesterday. No breakfast (mistake). Two bottles of Cytomax (maybe 400 cals), a double latte, and 5 boiled baby potatoes with parmesian and a dab of coconut oil. I almost blew chow on a 3 mile climb......it came right after the latte.

On longer ride, I try to get at least 300 cals per hour down but for me it depends upon pace. If I go really hard, it seems the digestive track stops. Going at a slow pace, I can eat and process a lot of material.


On a 200k with almost 10k climbing, I consumed around 3000 cals and also electrolyte replacements. No problems on the whole ride.
