Common sense tells us that running places a lot of stress on our joints, particularly the knees. We've all heard I'm sure that every time we take a stride whilst running we're placing '3 times our body weight' through our knee joints. Repeat this hundreds of times for each run, multiplied by many years and your knees are surely going to suffer?

The modern elite athlete is the product of genetics, top level coaching, years of hard training and cutting edge sports science. The most sucessfull Olympic nations invest heavily in the latter but occasionally however, even the greatest athletes in the world think that alternative practises will give them an advantage! (and in this case, I'm not talking about doping!)
