Race the Route: Train in the Lake District Year-Round — A Keswick Base Camp Guide

This is a Race the Route companion guide — pairing live event coverage with destination guides for athletes.

The Keswick Mountain Festival packs 18 sports into one weekend. But the Lake District does not need a festival to be one of the best multi-sport training destinations in Britain. The fells, lakes, and roads around Keswick offer world-class terrain for trail runners, cyclists, swimmers, and hikers — year-round, in all weather, and often with nobody else in sight.

Here is your training guide to using Keswick as a base camp.

Trail Running

The northern Lake District is fell running heartland. The terrain is steep, exposed, and relentlessly varied — perfect for building the kind of strength and mountain fitness that transfers to any trail race.

Skiddaw (931m) — The classic Keswick fell run. The standard route from Latrigg car park gains 700m over 5km to the summit. It is runnable all the way on a well-maintained path, with panoramic views from the top across the Solway Firth to Scotland. Fast runners summit in 40 minutes; most take an hour.

Blencathra (868m) — More dramatic than Skiddaw and with more route options. Sharp Edge is the famous scrambling route along a knife-edge ridge — not for the faint-hearted, but one of the great mountain experiences in England. For runners, the Blencathra fell race route via Halls Fell Ridge is steep, direct, and exhilarating.

The Derwentwater Loop — A 17km circuit around Derwentwater on paths and trails, passing through Grange, Lodore Falls, and the wooded shores of the lake. Mostly flat with short climbs. Perfect for recovery runs or long easy efforts with constant water views.

Cycling

The roads around Keswick range from gentle lakeside loops to some of the steepest passes in England.

Round Derwentwater — A 16km circuit through Grange and Portinscale with views of Blencathra and the Skiddaw range. Mostly flat with one short climb. Perfect for warming up or recovery spins.

Honister Pass — The road from Borrowdale over Honister to Buttermere is one of the Lake District's great cycling climbs. Steep, narrow, and dramatic. The descent into Buttermere valley is worth every metre of climbing.

Whinlatter Forest — Mountain biking trails ranging from family-friendly green routes to black-graded singletrack. The Altura Trail is the signature loop — technical, undulating, and with views across Bassenthwaite Lake.

The Back O'Skiddaw Sportive Route — The 100km road route used by the Keswick Mountain Festival winds through Cumbria's most spectacular landscape. Rolling roads, sharp climbs, and views that make every hill worthwhile.

The Lake District's lakes are some of the cleanest and most beautiful open water swimming venues in the UK.

Derwentwater is the obvious choice from Keswick — swim from Crow Park beach with Skiddaw rising directly behind you. Water temperature ranges from 6C in winter to 18C in summer. Wetsuits recommended October to May.

Bassenthwaite Lake offers quieter swimming with fewer boats. Thirlmere, south of Keswick, is a reservoir surrounded by forest — atmospheric and cold.

Swimming events at the Keswick Mountain Festival cover 750m to 3.6km in Derwentwater. But any calm morning offers the same experience without the crowd.

When to Train

Spring (March-May): Fells are greening up, roads are quiet, lakes are cold but swimmable. Best time for fell running before summer crowds arrive.

Summer (June-August): Longest days, warmest water, best weather. Also the busiest period. Early mornings are key.

Autumn (September-November): Spectacular colours, crisp air, emptying trails. Water is still warm from summer. Many athletes' favourite season.

Winter (December-February): Cold, wet, and dark — but the fells in winter are magnificent. Snow on Skiddaw and Blencathra transforms the landscape. Ice and wind demand respect and proper kit.
