I ride 12 km each way, 5 days a week. I go to sleep at 11 pm each night, a bit later on Monday nights. I get up at 6:20 for a 7 am departure. I do get 30 minutes to an hours nap each day.

Tuesdays are my difficult day as I have to work until 9:30 pm that night, riding home at 10 pm.

My guess, eat more. I eat mueslli every morning, and a big lunch.
