5-7 May - How will the weather affect this year's Ten Tors challenge? Check the forecast for Dartmoor.


You can also check to see if there have been any weather warnings issued that will affect Dartmoor National Park over the Ten Tors weekend.

To find out further information about the event, visit the Ten Tors website.

The challenge

400 teams of six take part in the challenge to complete the course. There are three different course lengths, depending on the age and ability of the team:

  • 35 miles
  • 45 miles
  • 55 miles

The idea of the challenge is for the teenagers to become self-sufficient for the weekend - carrying everything they'll need for the trek and making their own decisions.

Ten Tors and the weather

The weather has played a major part in previous Ten Tors challenges. In 1998, high temperatures meant there was a severe risk of dehydration for the participants. However, two years before that, there were severely low temperatures and Dartmoor National Park was struck by a sleet and snow storm which led to the military having to rescue some of the participants.

Take some time to watch this series of short videos on the skills needed to stay safe both out on the moors and the mountains.

Good luck to all those taking part in this year's event.
