Jenn Shelton

In July 2010 Shelton won the Deseret News Marathon in a time of 2:54:23. She says that she finds marathons more challenging to run than ultramarathons. Shelton has said that she intends to run more marathons and shorter races, citing a desire to run faster races. She is sponsored by Patagonia and competed in the 2012 U.S. Olympic Marathon Trials, but suffered a hamstring injury and did not finish.

In May 2007 she gained publicity by being the first woman at the Frederick Marathon in a women’s course record of 2 hours 53 minutes 44, racing in a bikini rather than conventional running kit.

In 2006, she traveled with Scott Jurek, Christopher McDougall, and several other ultrarunners as the sole female runner to Copper Canyon in the remote southwestern part of the state of Chihuahua in Mexico to run with the Tarahumara, for McDougall's book Born to Run. While running through a remote area during the trip she became separated from the group and was found severely dehydrated several hours later by a search crew. She has criticized the book's accounts of the Tarahumara people for "romanticizing" their lifestyle and for not adequately describing their poverty.

Jenn Shelton (born 1983) is an American ultramarathoner. She has set course records in several of the most demanding American ultramarathons.
