Hey runners, in today’s newsletter, PUMA is going its own way on super shoes.

The FAST-RB NITRO Elite 2 lands October 28 at €350 with two carbon plates, making it the brand’s second shoe that breaks World Athletics rules outright, in a market where everything elites can actually race in keeps getting lighter.

Elsewhere, Valencia’s final start lists are out, with Kenenisa Bekele entered a month after pulling out of Berlin. John Korir has signed with COROS through LA28. And we’ve taken a look at what the Jepchirchir EPO case means for Irine Cheptai, who may be named Sydney champion months after the race.

And as always, we round things out with the practical stuff: 11 reasons to run in the morning, six interval workouts, and an honest look at whether marathons are actually bad for you.
