8 pro cyclists who blitzed running a marathon (but who's fastest?)

BikeRadar recently published an intriguing piece highlighting eight professional cyclists who have completed marathons, comparing their respective times. While the article doesn't name all eight, it prompts a discussion around the surprising endurance capabilities of riders like former pro Laurens ten Dam, who clocked an impressive 2:58:04 at the 2023 Rotterdam Marathon, and former Team Sky rider Christian Knees, who finished the 2023 Berlin Marathon in 2:50:56.

This fascination with cyclists' running prowess isn't new, often surfacing during the off-season or as riders transition from their careers. It speaks to the broader athletic foundation required for elite cycling, extending beyond mere pedalling power. These marathon times, particularly those under three hours, demonstrate exceptional aerobic capacity and mental fortitude, challenging the notion that cycling-specific training renders other endurance disciplines impossible, or even just difficult.

Ultimately, it’s a fun diversion, reminding us that these athletes are, first and foremost, finely tuned endurance machines. But let’s be clear: a fast marathon time doesn't win you a Grand Tour.
