Originally an event for multiple shorter distances, the Personal Records Race evolved to an indoor ultra marathon. The first 24H event took place in Telekonsult Arena in 2013, on a 239 m mondo track. This year the track will be a 377 m lap on tartan surface, in the adjacent Tipshallen.
There are events for 6H, 12H and 24H. The event has a good reputation for being well organized, with food being served every 4-5 hours, drinks and light food is served continously, lap times can be seen on a TV screen and the race can be followed live, both split times and web streaming.
