KrUltra is short for 'Kruke's Ultra', and serves two main purposes:
- To organise and promote local ultra running and trail running events
- To help register and report on running events on behalf of other race organizers (Trace de Trail, ITRA, UTMB, NFIF, Kondis etc.)
Main focus is on ultra trail running in Norway, and West- and Mid-Norway in particular.
The main event organized by KrUltra is Kruke's Ultra-Trail Challenge (KUTC).
