The Rasselbock 545
The Rasselbock 545 on 25 July 2026 is a time-based track running challenge based at Horspath Athletics Track, just east of Oxford city centre.
Runners complete as many loops of the 400m track as they can in their chosen time limit. There are 6 (day or night), 12 (day or night), 24 Hour and 48 Hour options.
It is called the Rasselbock 545 as this this the number of laps you have to complete to beat the current track record. The challenge is to hit the next multiple of 5 and in doing so, pocketing prize money.
