Welcome to the Beautiful Bewl Water Swimrun! 


We’re absolutely thrilled to be back at beautiful Bewl Water for another exciting edition of our swimrun adventure. This truly is one of the most scenic venues in the UK –  and we’re privileged to race here with the kind permission of the Bewl Water team. 


The Courses 

All races feature easy swim entries and exits into the reservoir, and undulating run sections on a mix of trails, tracks, fields, and woodland paths.


6k & 10k: Start by heading across the dam wall, out through the woodland, into the water, before winding your way back through beautiful terrain to the finish.


 21k: You’ll head straight downhill and into the water, before heading out on a challenging loop around the reservoir. Expect epic trail sections, quiet country roads, steep hills, and a great adventure through the scenic Kent countryside.  The final run stretches feature grass tracks and wooded areas, with a couple more swims before you make your way back around to the finish line
