Breca Buttermere

29th July 2017

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.

The Lakes are also a mecca for endurance sports. It is the heartland of the UK fell running scene; it plays host to some of the UK’s most arduous challenges, attracted by its peaks, glaciated valleys and unparalleled network of trails.

When deciding where to host the UK’s first swimrun race in 2015, we were drawn to the Lake District. We were looking for a place that encapsulated the swimrun ethos: wild, exploratory, removed from artificial surfaces and structures; a setting where the challenges of the natural landscape would be central to the experience.

We found that place in the Buttermere and Borrowdale valleys. There is a horseshoe of lakes to explore – Loweswater, Crummock Water, Buttermere and Derwent Water – linked by a spidery network of paths and trails. The course encompasses waterfalls, exhilarating Lakeland ridges, island crossings and some of the most spectacular views in the Lake District National Park. It’s a linear route that progresses from the low hills flanking the Cumbrian Coastal Plain into the high fells of Buttermere, before dropping into the Borrowdale valley to the finish in Keswick. It’s a journey that will test you on many levels: the lakes are cold and deep; the ascents are savage and the descents are technical. It’s a course that favours the complete athlete.

Breca Buttermere is an ÖtillÖ Merit Race, offering ÖtillÖ merit points and the possibility of racing in the Swimrun World Championship in Sweden. To find out more click here.
