We have superb 6k, 10k and 21k swimrun courses with super open water swimming here at Bewl Water
The 6k and 10k courses head along the dam and out into the countryside before weaving their way back towards the finish. The 21k runs down from the start and the first swim takes you across in front of the dam wall. Catching up with the 10k course for the next few swims it then continues all the way around the reservoir. It covers some awesome trails, quiet roads and serious hills on a run through and around the nature reserve . Grass tracks take you back into wooded areas for a couple of swims before heading back around to the the finish.
