About this episode
With the 2025 marathon season just around the corner, our editors Alex, Katelyn and Michael ask: who (if anyone) will finally break the two-hour barrier on a legal marathon course? They explore the science behind running a sub-two marathon, the evolution of shoe technology, Eliud Kipchoge's Breaking2 and INEOS 1:59 Challenge events, and the haunting spectre of the world record holder, late Kelvin Kiptum. They then get into where, when and who could finally break this elusive barrier in distance running. Come see our live podcast at the Boston Run Show! March 1-2.
