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.Time stamps: 00:00:00 — Introducing Jimmy Whelan 00:03:43 — New Shoes & Faster Workouts 00:06:31 — High School Running to Pro Cycling 00:09:58 — Did Cycling Build His Engine? 00:13:51 — Rediscovering Running’s Simplicity 00:17:32 — Cycling’s Aerobic Advantage 00:29:59 — Training Volume: Cycling vs Running 00:34:15 — Identity Shift from Cyclist to Runner 00:42:25 — Valencia Breakthrough Performance 00:52:30 — Elite Cycling Habits in Running 01:06:18 — Jimmy’s Running Training & Treadmill Work 01:15:35 — Big Goals: Pro Contract, Marathon & Olympics 01:22:00 — Final Thoughts & What’s Next🎁 Partner OffersGet 20% off a STRAVA annual subscription with code KRISTIANGet €15 off AG1:https://fbuy.io/greens/nmnk5mmySave on FlexBeam using this link or code WARWICKRUNS:https://rechargehealthas.sjv.io/55GAPbStart your free Musicbed trial:https://fm.pxf.io/kristianwarwick🎥 Full episodes + the Boston 2025 documentary:https://www.youtube.com/@Warwickruns📸 Follow Kristian’s journey on Instagram: @warwick.runs🎶 Music from Musicbed: MB01XPYH8ZYENVAMB0133EV2TCQFZY🔗 Watch & Follow
