Are you building mileage too FAST?


Newsletter #887: Tuesday, August 11, 2026


Hey runners,

We’re kicking off the week with plenty of practical advice for your training: how to use the 10% rule to safely build mileage, whether running can really help ease anxiety, what to eat the night before a long run, and a full-body, runner-specific strength workout to add to your routine.

In the news, an authorized Lazarus Lake documentary is premiering during UTMB week, 10 American women broke 4:30 in the same mile race, the Sydney Marathon is turning race week into a citywide perks program, and we’ve got all the track results from the 2026 World Athletics U20 Championships.

And if you’re ready for your weekly running-news catch-up, there’s a brand-new episode of The Running Story, where Michael and Jessy break down the biggest stories from around the running world this week.

Happy running!

The Running Story: Cambridge Professor's Running Claims Unravel, NYC Marathon's New Lottery & Stroller Mile Record

This week on The Running Story, Michael and Jessy break down the five biggest stories in the running world. The New York Road Runners have quietly added a new lottery to their guaranteed-entry 9+1 program, making it even harder to get a guaranteed bib into the New York City Marathon.

Grand Slam Track founder Michael Johnson breaks his silence for the first time since the league collapsed into bankruptcy, giving his first interview since GST folded, owing athletes and creditors millions of dollars.

Plus: a runner just set the fastest stroller mile in history on the Guardian Mile course, a viral video shows a Mexico City Marathon bandit runner being tackled by a race official, and Cambridge sociology professor Jason Arday's wild endurance-running claims are being called into question as his academic record comes under fire.
