One of the main reasons for a DNF in an ultra is nausea and vomiting (23% of DNFs at the 2009 WSER were for this reason). Even among those that finished, up to 40% of the Western States field experienced nausea and or vomiting that affected race performance. Stomach problems can sabotage all the hard training you have done so it’s critical you have a strategy that works for you going into a big race.
Nutrition is a complicated topic but I’d like to break it down to 4 main questions:
- How much should I eat?
- What should I eat?
- When should I eat?
- What to do if something goes wrong?
