Larry Warbasse ended 2023 on a high – literally – after setting a new Strava KoM on one of the world's toughest climbs.

The Mauna Kea volcano climb in Hawaii is 89.5km long, beginning at sea-level and topping out at a dizzying 4,214 metres. Decathlon-AG2R La Mondiale rider Warbasse completed it in 4.59.04, taking just 15 seconds off the previous best time set by former pro rider Phil Gaimon in 2016.
