From the the event’s above website, the adidas TERREX STING adventure race is described as:
“A five day non-stop adventure race for teams of four. The event is an expedition race with few control sites spread across a huge area of the country. However, there will be some fine navigation in some parts of the event and special challenges. The winners are the team which cover the entire course in the least time”.
Disciplines to be completed over ten stages include running, mountain biking, lake canoeing, mountain trekking and whitewater canoeing.
