Scott Jurek

Why is he the greatest endurance athlete?

- He is one of the most popular ultramarathon runners, with a huge Facebook following.
- Despite winning the Spartathlon three times in a row and the Western States 100-mile run six years in a row, Jurek has a light-hearted approach to running: screaming at the beginning of each race, rolling over finishing lines and staying behind for hours to cheer late finishers.
Pam Reed

Why is she the greatest endurance athlete?
- Pam Reed is one of the few women to win an ultramarathon outright.
- She didn't just win any race, but one of the toughest the world, the Badwater UltraMarathon, a 135-mile run through Death Valley in temperatures of 50 degrees Celsius in the shade, finishing five hours ahead of her nearest male competitor.
- The 5 foot 3 inch tall mother-of-five was 41 when she won the Badwater in 2002, and for good measure won it outright again the next year.
- Reed once completed a 300-mile run without sleep.
Mark Allen

Why is he the greatest endurance athlete?
- Allen won the World Champion Ironman triathlon six times – a 2.4-mile open water swim, 112 mile bike ride and full-length marathon.
- He also won the World Champion Ironman triathlon five times in a row from 1989 to 1993, when he set a world record of 8 hours and 7 minutes that lasted until 2011.
- Best nickname in the sport: The Grip, as in, 'of death'.
Chrissie Wellington

Why is she the greatest endurance athlete?
- In the biggest shock in the sport, Chrissie Wellington won the Hawaii Ironman triathlon on her first attempt in 2007, then continued winning the next three world championships she entered.
- Wellington holds all three Ironman triathlon record times and the next four fastest times.
- She only started running in her mid-twenties as a way to lose weight. She has also overcome a major bike crash before her 2011 championship and in 2008, still won despite losing ten minutes because of a flat tyre.
- She's British.
