I just came across an article about 18 people in the U.K. will be attempting to run 10 marathons in th 10 days in May when they will be attempting the Brathay 10 in 10. So far, 32 people have completed the 10 in 10 since 2007.
In case you are wondering, the 10 in 10 involves running the same route each day around Lake Windermere, the largest natural lake in England.
I can’t imagine running the same 42 km route for 10 straight days. I would have to imagine that days 6 and 7 would be tough mentally.
