You might remember I've posted about my friend Mark Burson before...  he's a cyclist who had to have his hip replaced, after which he became a significantly more serious cyclist.  He got me into ultra cycling, and in 2008 we completed the California Triple Crown together, just before the first anniversary of his artificial hip.

So he hasn't stopped there; he's gone on to ride the Race Across the West, and is now entered as part of a four-person team in the Race Across America (RAAM), possibly the most arduous cycling event of them all.  Congratulations and best of luck to him and his team!
