My mate
wascally_weasel is on his way to Land's End today, for the epic charity undertaking The Race Against Time. He and his eight-strong team will be cycling from Land's End to John O'Groats for charity. But because that would be too easy, they have to do it in six days. Which means a week of hard cycling, needing experienced and quick riders, top kit and serious team tactics and support. something like 150 miles per day. Day after day. He's blogging about it
here, and will be
Tweeting en route.
Good luck, mate!
