The following is a list of totally awesome runners.
If you think running a marathon (26.2 miles) is nuts-then Geoff Roes is really going to make you dizzy. He is currently the best ultra-runner in competition. The races he has won include the Western States Endurance run (100 miles) which he set the course record last year (15 hours and change). He has a long list of other wins (American River 50 mile, Susitna 100 mile, and just two days ago he won the Zane Grey 50 in 8 hoursish). I like to think of Roes as an unofficial Toilet-Runner because he often crosses the finish line and proceeds to throw up 3 or 4 times. http://www.akrunning.blogspot.com/
Sandes is a South African beast of a runner. He is currently the only person in the world to have won every race in the grueling 4 deserts racing series. 4 Deserts consists of four races through the worst desert conditions on the planet (Atacama, Gobi, Sahara and Antarctic deserts). At each race you run for 7 days and have to carry all of the food and water you need and are only allowed a tent to sleep in. Sandes won every desert last year by a gigantic margin easily crowning himself the 4 deserts champion. Not even Dean Karnazes (who only won 3 of the deserts) was able to do what Ryan Sandes did. http://www.ryansandes.com/
“Retired” Runners of Note
Scott Jurek-Easily the greatest Ultra Marathoner of all time (won Western States 7 years in a row)and countless other Ultra Marathons. http://www.scottjurek.com
Hunter Kemper-3 time Olympic Triathlete: upon investigation I learned he is NOT retired-and won Gold 2 days ago at a World Cup Triatholon. http://www.hunterkemper.com/
