In Episode 61 of the Kinda Fast Podcast, Claire and Travis are answering a question every runner eventually asks: When is it actually time to increase your mileage?

But first, they kick things off with What Does That Even Mean? and finally settle the question of what exactly a running singlet is—and whether it’s really any different from a tank top.

Then it’s time for running news! The Tokyo Marathon 2027 lottery is officially open, and Claire and Travis break down the important dates, entry fees, and just how tough it is to land a bib.

They also test out a viral running hack involving Aquaphor on your eyebrows to keep sweat out of your eyes. It sounds ridiculous…but apparently there’s actually some science behind it.

And the Jakob Ingebrigtsen vs. Josh Kerr rivalry is back. After returning from 11 months away from racing, Jakob says athletes who skip major championships are “ruining the sport”—and yes, he was talking about Josh Kerr.

Then, in today’s Deep Dive: Kinda Want to Run More Miles?

Claire and Travis talk about how to know when your body is actually ready for more mileage, including:

• Whether you’re consistently handling your current mileage
• How well you’re recovering between workouts
• What your easy pace can tell you about your fitness
• Why mileage increases should support a long-term goal
• How structured training plans can help take the guesswork out of adding miles
• When the 10% rule can be useful
• Why you should spread extra mileage throughout the week
• Why adding mileage AND intensity at the same time can be a mistake
• Why you should never try to “make up” missed miles

The biggest takeaway? More mileage isn’t automatically better mileage.

The goal isn’t to run the most miles you possibly can. It’s to find the amount of mileage you can train from, recover from, and consistently repeat.
