Your long run feels great through mile 5 or 6. Then somewhere around mile 8, everything starts falling apart.

Your legs get heavy. Your pace slips. The remaining miles suddenly feel enormous. And if you're training for your first half marathon, you may start wondering how you're ever going to make it to 13.1.

Here's the important part: there's nothing magical about mile 8. The problem often started much earlier in the run.

In this episode, Coach Chris and Coach Maya break down why long runs can unravel late—and what beginner runners can do to prevent it.

You'll learn:

• Why starting just a little too fast can come back to haunt you miles later
• Why “banking time” early in a run often backfires
• Why fueling before you feel depleted matters
• Why fueling by time can make more sense than waiting for a specific mile
• How heat and humidity can make your normal pace unsustainable
• Why your endurance may simply still be developing
• How to handle the mental battle when the final miles start feeling much harder
• What to do differently on your very next long run

Our biggest takeaway?

Mile 8 usually isn't the problem. What happened before mile 8 is the problem.

And you don't solve mile 8 at mile 8. You train for it.

Running advice is everywhere. Unfortunately, a lot of it is outdated, oversimplified, or just plain wrong.

In this episode, Coach Chris and Coach Maya separate popular running myths from evidence-based coaching to help beginner runners train smarter, avoid injuries, and enjoy the process.

We tackle everything from "no pain, no gain" and forcing your running form to stretching myths, carbon-plated super shoes, chasing mileage, and why trying to copy elite athletes can actually hold you back.

In this episode, you'll learn:

• Why "no pain, no gain" is one of the worst pieces of running advice
• Why easy runs are essential for building endurance
• Why most beginners don't need to overhaul their running form
• How a small cadence adjustment can improve running efficiency
• When carbon-plated racing shoes actually make sense - and when they don't
• Why dynamic warm-ups beat static stretching before a run
• Why sudden long-run increases matter more than chasing weekly mileage
• Why consistency beats perfection every time

The truth is that successful runners aren't usually the ones chasing every new trend—they're the ones who consistently follow the fundamentals.
