New to Swimrun?

Welcome! As a Breca Swimrunner, you will take part in ultimate endurance challenges through incredible landscapes carefully selected to fulfil your desire for adventure, a break from the norm and for paths less trodden.

The three key things to know about swimrun are:

  1. You switch between swimming and running many times during the race
  2. You participate in pairs, making it a team event
  3. You swim in your trainers and run in your wetsuit – there are no gear changes

Testimonials from previous breca swimrun participants

Such an awesome event, and Jersey provided such an exciting & challenging venue for this.
I really wouldn’t hesitate in recommending Breca SwimRun, they have been absolutely amazing.
EPIC EVENT. Amazing checkpoints, beautiful location (gutted I didn’t have a GoPro with me), challenging course, amazing marshals.
If you’re looking for something a little different, set in one of the countries most beautiful areas, a really challenging course, and you get to race with a partner, this race has to be top of the list.
Fantastically organised and ran event with that back to basics feel about it.
Thoroughly enjoyed it and can’t wait to come back next year for more of the same.
Amazing opportunity to race in the Lakes.
Organisation - the race was extremely well organised. We had all the information we needed to enjoy our adventure in the lakes.
Course design - absolutely stunning! Such an interesting course.
Not for the fainthearted - you needed to have your wits about you!
Scrambling up rocks, navigating paths skirting edges of high climbs whilst being blown towards the edge added an element of thrill to the event!
You could go for absolutely ages without seeing  a marshal too; but in my mind this added to the ethos of the event - just you and your partner being self sufficient to get to the finish!
