Relisten to one of the most popular episodes of The Marathon Podcast:

How does an athlete go from professional cycling to elite distance running — in less than a year?

In this episode of The Marathon Podcast, Jimmy Whelan joins the show to discuss his remarkable transition from WorldTour-level cycling to professional running. After years racing internationally with EF, Jimmy stepped away from cycling — and within a year ran a sub-30 10K and a 61-minute half marathon, earning his place as a professional runner.

We talk about the differences between cycling and running, how aerobic fitness transfers, what surprised him most about running training, and how he’s preparing for his first-ever marathon. This is a fascinating look at elite endurance performance, adaptation, and what’s possible when world-class fitness meets a new discipline.

A must-listen for runners, cyclists, and endurance athletes curious about cross-training, aerobic development, and marathon potential.
