Welcome to the KrUltra web site!

Here you will find info about KrUltra activities. KrUltra is short for 'Kruke's Ultra'. KrUltra has two main purposes:

  1. Arranging and promoting running events
  2. Registering (Trace de Trail, ITRA, UTMB) running events on behalf of other race organizers

The main event organized by KrUltra is Kruke's Backyard Ultra-Trail Challenge (KBUTC).
