Breca Buttermere

Next event: 11-12th August 2018
Location: The Lake District, England

Imagine a land of extremes: the home of England’s highest mountain and its deepest lake. An ancient landscape of craggy hilltops, mountain tarns, rugged trails and glittering lakes. That place is the Lake District National Park, and for centuries it has captivated the imagination of adventurers, explorers and intellectuals alike.

This is the setting for Breca Buttermere - the UK's original swimrun race. The courses will test you on many levels: the lakes are cold and deep; the ascents are steep and the descents are technical. It’s a course that favours the complete athlete.

Mandatory kit

Each team must have:

  • Two wetsuits suitable for temperatures of 10°c
  • Two whistles
  • Two reusable cups or flasks - any kind will be accepted, as long as they are genuinely reusable

Teams may also use tow ropes, paddles, pull buoys and fins (no longer than 15cm, measured from the toe), but they are not mandatory.


Being part of the Breca Buttermere Event Team is rewarding and fun. If you can commit to a full day of volunteering you will receive a t-shirt, lunch and free entry to a Breca Swimrun race the following year. Click here to find out more.


Supporters are more than welcome to attend the event and we hope to see you especially at the finish lines and the post-race social.

We ask that you observe the following advice:

  • Please do not accompany competitors to the race registration and briefing. The venue is not big enough.
  • Please do not attend the race start of the full or sprint distance races. The start locations are restricted spaces with no spare parking and narrow roads.
  • Please use designated public car parks and don’t park on private property or roadsides.
  • The best places to watch the races are on the shores of Crummock Water and Buttermere which both have many footpaths around them. There are small car parks along the B5289 and in Buttermere village, which also has cafes and pubs.

The finish area of the Buttermere Sprint will be on the lakeshore of Buttermere, at Hassness. Please park in Buttermere or at the car park at Gatesgarth and walk to the field, as there will be no parking there. Please DO NOT enter the Hassness House driveway as the finish area is not accessible from there.

There is a good footpath around Derwent Water but not much parking at the southern end near Manesty where the full distance competitors descend from the fells. Much better to cheer them on at the last swim exit near Crow Park, or at the finish.
