In Episode 642 of “The Livin’ La Vida Low-Carb Show with Jimmy Moore,” Jimmy Moore interviewed an ultra runner and low-carb endurance athlete Timothy Allen Olson. Over the last few years, he has switch to a low carb diet,while in Ketosis, with amazing results.
In 2012 Olson not only won Western States 100 in a time of 14:46:44, but smashed the course record by over 21 minutes on a course considered significantly slower than either of the courses used for the previous two course records. Very interesting and worth checking out . . .
Here is another interview from iRunFar talking a little more about the race itself. http://www.irunfar.com/2012/06/timothy-olson-2012-western-states-100-champ-interview.html
