Austrian ultra-cyclist Christoph Strasser rode 941.873 kilometres in 24 hours on the indoor boards of the Velodrome Suisse, setting a new WUCA-ratified world record. The ride, completed on 15 October 2017, required 3,767 laps of the 250‑metre oval in Grenchen, Switzerland, at an unrelenting average speed of 39.42 km/h.
A fight against the stomach and the lap counter
The attempt began at 1pm on Saturday afternoon amid the buzz of the Specialized‑Days event, where 500 guests tested road bikes beside the track. Four hours in, the pressure of Strasser’s aerodynamic tuck triggered stomach trouble that forced his support crew to rethink his fuelling plan while he kept pedalling. He stopped just once in the full 24 hours — a single three‑minute pause after the twentieth hour.
Baloh’s mark reeled in, then left behind
The record had belonged to Slovenian Marko Baloh, and Strasser overhauled it shortly after the 23‑hour mark. Once past that threshold he pressed the advantage, circling into fresh territory beneath the bright velodrome lights. No other human had ever pedalled farther on a track within a single calendar day.
Strasser already owned the outdoor 24‑hour road record of 896.173 km, set in Berlin in 2015, and had crossed continents in days, from Perth to Sydney and from coast to coast across America. Yet the velodrome effort asked a different question — one of pure repetition, where the scenery never changed and every lap demanded a decision to continue.
A gruelling mental geography
Ahead of the ride Strasser had called the attempt “the most difficult and boring thing you can do” on a bicycle, adding that “the mental effort to fight against boredom plays a major role.” Afterwards, he placed the day among his hardest. “I’ve ridden across continents, I set the 24‑hour outdoor world record in Berlin,” he told reporters. “But almost nothing else compares to today.”
He had won the Race Across America six times by career’s end, become the first to break the eight‑day barrier there, and returned from a training crash that fractured his kneecap. The Grenchen ride, however, was a quiet siege — 3,767 laps without a single shift in the view, and a distance that would stand as the indoor benchmark for years.
