Dean Karnazes does 50 marathons in 50 days

I wrote about seeing Dean Karnazes speak at REI some time back. One thing that he mentioned was that he was going to run 50 marathons (each in a different state) in 50 days which he did. This should surprise no one however the day after finishing the 50th (New York Marathon) he ran the course in reverse and then ran another marathon distance the next day (52 marathons in 52 days). So how does he top that? By running back to San Francisco!

Also, the trail running shoes that Dean was developing with North Face that I mentioned (or some variation thereof) are now available - I tried them out in Chicago recently and the lace ratcheting thing really works well.
