More tired after a rest day

[Heretic]

I posted this link to a podcast about nutrition in another thread:

Nutrition for Endurance Biking

I suggest listening to this podcast where this topic is discussed (among others): One of the key ideas is that you need to focus not just on fueling for the race, but keeping your glycogen stores filled all the time. In endurance events you will almost always deplete your stores faster than you can replenish them. If they are low to start, you will not perform your best.
