In endurance racing, you usually have one hour's riding followed by two hours of 'rest', but it's almost impossible to sleep. I usually need physiotherapy after each session because I'm tall and get a sore neck from racing at high speed for sustained periods. I always need a good massage to get me ready for the next session. You also need to speak with the team, eat, and get to the pit garage at least 20 minutes before you are due out again. However, I do usually reserve one rest period for sleeping, and I need this most at about four or five o'clock in the morning. I used to never sleep when I was a younger rider but it's so important to know what your body needs. I am stricter now and need sleep more!
