However, as someone who has learned the benefits of being healthy the hard way - through real exercise - I'm convinced this is one short-cut to fitness that's going to lead us to a dead end. Just as you cannot substitute a well balanced diet with a vitamin pill, an exercise pill cannot replace a healthy lifestyle.
I have a lot of people to thank, everyone who donated to the charity, to everyone for their messages of support, my friends family and work colleagues, Tom, everyone at Psycle and everyone involved in the world marathon challenge; the organisers, the volunteers, the support crews and my fellow runners.
Zátopek's commitment to self-torture encourages us to do anything but spare ourselves the ordeal of going out in the rain or wind. When you next approach a treadmill, think of Zátopek running through deep sand in heavy boots - and consider where it got him.

ailing the Endurance down the curving arm of the Antarctic Peninsula, Shackleton planned to disembark with six handpicked men and attempt a death-defying 1,800 mile trek across the Great White Continent on foot: through the South Pole and straight out the other side until they hit the frozen coast again.
