often times i go out for a ride, feel good for the first 4 miles or so while i'm warming up with some easy spinning. then i hit a dead spot and my legs feel like logs and my motivation drops off dramatically (sometimes i feel like heading home right then). but i find i can pedal right through it and get a 2nd wind which lasts until the end of the ride.

i really hate that dead spot of my training. what do you think causes it? is it diet or is it a mental thing? almost without fail i have a banana, clif bar, and a piece of wheat bread with a little peanut butter before i head out.
