Sprint Training for Faster Marathons

Recording from Beijing International Airport during a delayed Air China flight, I share a short, single-topic episode exploring the "speed gap" and why pure speed can be a major limiter for marathon and half-marathon performance.
Using examples such as breaking three hours in the marathon and my own goal of running 2:19, I explain why runners need enough speed at shorter distances to make marathon pace feel sustainable. I also discuss why many runners and coaches place too much emphasis on mileage and threshold training while neglecting speed development.
I finish the episode by sharing three practical ways to improve speed without dramatically changing your training: short max-effort hill sprints, regular strides after easy runs, and strength training focused on squats, hamstrings and calves.
