SWIMRUN

Swimrun is an adventure race with swim and run sections. The emphasis is on adventure...navigating a course through woods, paths and trails and using naturally occurring swim entry and exit points. There are no transitions, any kit you use you carry with you. The courses are signed and tape is used for you to follow the course. You need to be aware, self sufficient and be able to follow signs. It is an awesome experience which puts you in touch with nature and awakens the adventurer in you!

To have a go...

You just need to be physically fit enough and capable of swimming in open water and running on mixed terrain over the race distances.

What you need...

You will need to wear your running shoes/trainers throughout the event and you will need to wear a wetsuit, tri-suit or swimming gear. You can use additional equipment such as paddles and pull buoys but whatever you start with you have to carry and finish with.
