Most people couldn't run a marathon if their life depended on it, but world-record juggler Joe Salter ran the whole 26.2-mile Quad-Cities Marathon backwards while doing what he does best, juggling.

32-year old Joe Salter can practice his juggling skills pretty much anywhere. In the past, he swam a half-mile in the Gulf of Mexico, doing the backstroke while juggling three balls. He also juggled for 16.2 miles on a bike and ran and juggled for four miles. He holds the world records for the fastest time while running a mile backwards and juggling (7 minutes, 32 seconds) and the fastest juggling triathlon (1 hour, 57 minutes). However, he was hungry for a Guinness World Record, so he challenged himself to run the entire Quad-Cities Marathon in Illinois backwards, while juggling. Unfortunately, Guinness rules are very strict, and for Joe's unique feat to qualify as a record, every second of the race had to be recorded, which was impossible since videotaping is prohibited along several miles of the course that run through the Rock Island Arsenal.

Although he was slightly disappointed, Salter found an upside to the whole situation. ”I actually feel better, not having the stress,” he said before the race, and indeed the lack of added pressure helped him finish the entire 26.2-mile marathon in just 5 hours and 51 minutes.
