How does a runner break through stagnation and start competing at a higher level?

In this episode of The Marathon Podcast, Alfie Manthorpe — the British runner everyone seems to be talking about — joins the show to break down his journey, his recent performances, and the training changes that have driven his progress.

We talk about Alfie’s background, his experience at altitude in Sierra Nevada, the three key pillars that transformed his running, and how he’s planning to approach the marathon distance this year. We also dig into fueling, easy pacing, self-coaching, and how social media has shaped modern British running culture.

A practical, honest conversation for runners looking to train smarter, stay consistent, and take the next step forward.
