Yes. You can give up for any reason (injured, don’t feel well, not having a good time, hungry, been out too long) but you must check in at the finish – otherwise we will think you are lost and launch a search and rescue mission.
Your result will be recorded as DNF “Did not Finish”. At orienteering events there are always a few people who DNF and there is no shame/failure attached to this. Don’t quit orienteering!
If you DNF on the first two days of the Turbo Chook 3 Days you are still allowed to start the next day(s) – it just impacts on your overall result.
