Barefoot 24hr Race - 165200 Meters or 102.65 Miles
Some say barefoot runners are crazy and I tend to joke about it too and talk people round to seeing my point of view, but Todd Ragsdale takes the biscuit. He's definitely mad: 102.65 miles around a 400 meter track for a new world record. You can see a news report from a local TV station too (how old is the article's reporter? 15? I feel so old).
