Bill Mayer talks about 24 hour races and his nutritional strategy for maximizing his performance.
Bud and Bill Mayer, president of the Michigan Mountain Biking Association, continue their conversation from Bill's last podcast by talking about 24 hour bike races (Quicktime ipod compatible, 81MB; Google streaming flash video). In a 24 hour race, Bill is actually on the bike for 23 of the hours! Bud observes that from where he sits, there is not much difference between 23 and 24, and Bill admits that no matter how you slice it, the races are quite intense!!
Bill then mentions that his lower back must be strong for these races because it helps with power generation on the bike. Bill races two kinds of bikes — those with gears (more than one speed) and also single speed bikes. He says that the single speed bikes test his low back and glute strength power. Bill's winter weight lifting program has helped. He has a meter on his bike that gauges power output and he has seen a definite improvement.
Bud and Bill next talk about Bill's diet. As it turns out Bill watches his diet quite closely. He had his basal metabolic rate measured by a device called the BodyGem and he uses an internet program to track what he eats. He says the tracking program has made him more aware of the quaility of food that he consumes and also more accountable for the choices he makes. Bill says that although tracking was tedious at first he now feels that it is easy and has become accustomed to it. Bill also mentions that tracking what he eats has allowed him to become aware of portion sizes that are appropriate for him. If he eats more than a certain portion he finds that he is lethargic and uncomfortable. Likewise, if he keeps his portion sizes in check he feels good and his energy level is high.
Bill and Bud finish the conversation on how diet affects performance especially as you get older. Both agree that if the quality of diet is strong it can help performance. Bill gives the example of the difference in age groups in cycling. He says that the 20-30 year olds are not as fast as the 30-40 year olds. He also says that the 40-50 year olds are the most competitive group. He believes this is due to experience and knowledge gained within the sport and also with diet and nutrition.
