Hey runners, in today's newsletter, the Alphafly 4 has landed and vanished.

Nike's new $280 marathon racer sold out in under five minutes in the US and even faster in Europe, with a wider release promised for October 29.

Elsewhere, an MRI has found Keely Hodgkinson's hamstring tendon split in two. Kenenisa Bekele will run Berlin at 44, his first marathon finish attempt since Paris. And John Korir says he's chasing a sub-two-hour marathon in Valencia in December.

And on an extra bright note, Brady McDonald ran a 50K in all 50 states in 50 straight days, covering 1,553 miles and raising $1 million for Make-A-Wish.
