Easily the largest timed ultra running event in Sweden and the only one indoors. This year with Växjö Löparklubb as the new organiser. For the 4th year the facility will be Tipshallen, on a 373 m tartan track.
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.
