The first two days of competitions will be held from the arena in Blomstermåla which is located 40km south of Oskarshamn. The other three days are held in close vicinity of Oskarshamn, this makes it possible for those staying at the camping or in town to bike to those stages. During stage 4 and 5 the MTBO arena will be located close to the runners arena, thus making it easy to socialize with your orienteering friends, clubmates and family regardless of whether you choose to run or bike your course.

Based on the description and pictures in the O-Ringen Magazine the baltic ocean coast offers magnificent beautiful forrests with path and track networks well suited for MTBO. More sparse network for the long distance and detailed for the sprint will be a perfect mix. Several of the forrests are used for regular mountain biking with trails maintained by the local MTB clubs.

You can take part in O-Ringen in several different ways:

  • 5-days MTBO classes: Competition class where the total time of the four first stages are summed up and at the fifth stage there is a chase start where the first over the finish line is the total winner. This is the classic competition format and still the most popular. The start times are drawn and assigned in advance, you choose a class according to your age.
  • Stage start: Open classes where you choose a course suitable to your own ability and experience. You select your own starttime at the start. Compete against your friends by “tagging” them in the time taking system. The open classes are for those who only want to bike on some of the stages or would like the freedom of selecting a different course every day.
