Sub-Ultra Marathon Training Guide

If you're preparing for a marathon or a shorter race, the longest run typically ranges from 18-22 miles for a marathon, 12-13 miles for a half marathon, and 6-10 miles for a 10K. However, the long run shouldn't be the sole focus of your training plan. In reality, endurance and fitness are developed with every run.

A training principle I've adopted from my ultramarathon experience is having my runners perform back-to-back long runs. I start incorporating this into their training plan early in their schedule. The second long run is usually half the duration of the previous day's run. The goal is for them to run on tired legs. This method enhances their endurance, boosts their confidence, and teaches them how it feels to run when fatigued.
