Why Most Marathoners Fall Apart After Mile 18

Most marathoners know the moment when the race really begins.

Around mile 18.

Up until then, everything feels controlled. The pace is steady and confidence is high.

Then the race changes.

Legs get heavy, the pace starts slipping, and the final miles turn into “just get it done” miles instead of strong execution.

What makes this frustrating is that this happens even after months of hard training. Long runs were done, weekly mileage was consistent, and the work was put in.

But many runners eventually discover the same thing:More miles alone don’t prepare the body for the hardest part of the marathon.

In this episode, we’ll break down why so many runners struggle after mile 18 and what actually helps runners stay strong in the final miles.

Using Bryce's story as an example:We'll cover what allowed a 3:27 FIRST marathon followed by a 3:37 finish on the hot and hilly (1000 ft climb) LA Marathon just one month later.

And here’s the surprising part.Bryce was over 250 lbs just a year ago and had only started running last year, dealing with foot, knee, hip, hamstring, groin, and IT band pain along the way.

But this episode is not just about Bryce.

It’s about understanding what allows some runners to stay strong late in the race while others fade.
