How fast can you REALLY race?


Newsletter #913: Thursday, September 10, 2026



Hey runners,

We’ve got a new podcast for you today! Michael, Alex, and I are covering everything from figuring out how fast you should actually race and chasing ambitious marathon goals to shoe rotations, injury cycles, ACL comebacks, and why fueling and recovery could be the missing pieces when your fitness says “go” but your body says “not so fast.”

We'll also take a close look at Altra’s first real super shoe, and catch up on the latest running news: Jenny Simpson opens up about the cardiac arrest that ended her running career, an incredible 4,500 liters of wine went out onto the course at the world’s drunkest marathon, and the start lists are out for the 45th Fifth Avenue Mile and the World Athletics Ultimate Championship.

Finally, today’s training guides cover how to calculate the right marathon pace and race smarter, everything runners need to know about nutrition, and a fascinating look at whether what we often call “overtraining” could actually be underfueling.

Happy running!

The Vanish Carbon 3 runs on a 4 mm drop, from the company that trademarked zero. A morning at Altra's Denver headquarters made the case that the number clarifies what the brand has always been about, rather than abandoning it.
