Running is actually good for your knees, if you haven't suffered knee injuries in the past. [D]espite entrenched mythology to the contrary, runners don’t seem prone to degenerating knees. An important 2008 study, this one from Stanford University, followed middle-aged, longtime distance runners (not necessarily marathoners) for nearly 20 years, beginning in 1984, when most were in their 50s or 60s. At that time, 6.7 percent of the runners had creaky, mildly arthritic knees, while none of an age-matched control group did. After 20 years, however, the runners’ knees were healthier; only 20 percent showed arthritic changes, versus 32 percent of the control group’s knees. Barely 2 percent of the runners’ knees were severely arthritic, while almost 10 percent of the control group’s were.

Unfortunately, it was proving difficult that day as the runners all seemed to prefer... nothing" - from Christopher McDougall's forthcoming book "Born to Run" which looks at the story the growth of the $20 billion running shoe industry. Starting form Bill Bowerman's Cortez in 1972 onwards runners have seen a steady flow of innovations to improve performance and reduce injury rates. Only it would appear they may not work. By way of contrast the book includes coverage of the Mexican Tarahumara tribe who run ultramarathons with shoes made from car tyres on their feet.

Joggers decked out in short shorts and iPods running alongside the road are common, but have you ever seen someone running backward? Backward running has been growing in popularity for years in many countries across the world where competitive races vary in length from sprints to marathons. This very different form of exercise is reputed to have many health benefits, despite the very obvious dangers of not being able to see where one is going. Think you can beat the current world records for backward running? If so, then this is the person you're going to need to try and beat...
