Ultra Trail Mont Blanc (UTMB) introduced strict anti-doping control measures this year. Blood, urine and even hair samples were tested from many top runners.
Topher Gaylord blogs, "...20 top runners were chosen to be tested... Scott Jurek and Nikki Kimball were also tested...".
Gaylord turned out to be the best American runner this year, finishing 11th in 24 hours 55 minutes. Jurek dropped out in Champex, after running 123K in 15:48. He was third when he decided to stop racing.
Surprisingly many UTMB 2007 top runners chose to drop out during the race. The weather was fine, but I'm sure they all have another excuse.
Men:
- Marco Olmo (1st UTMB 2007): dropped out at 149K (20h 58 mins).
- Jens Lukas (2nd UTMB 2007): dropped out at 108K (15:29).
