The Derwentwater Sport Trail is the shortest course at Lakeland Trails Keswick, yet it is no gentle starter loop: soon after the Fitz Park start it climbs through the steepest pitches of the whole event. Preparing for it means preparing for one hard ascent and a quick run back down to the finish.
Every race of the day sets off under the gantry in Keswick's Fitz Park. The first kilometre or so is close to level, then the main climb begins: around 125 m of ascent in roughly a kilometre and a half, with stretches steep enough that most runners will walk. By the high point, a little past two kilometres, most of the work is behind you.
The path then drops before a short second rise around the three-kilometre mark asks for about 30 m more. From there the last kilometre and a half runs downhill and finally level back into the park, where live music, food and drink are waiting at the finish.
The route uses fully marked and marshalled footpaths and bridleways around Derwentwater, with views over the lake towards Skiddaw and Blencathra. Most of it is hard-packed trail with the odd muddy section, plus short road stretches and private land that is only open on race day.
| Start | Length | Ø | Max. | Gain | Cat. |
|---|---|---|---|---|---|
| km 0.9 | 1.4 km | 8.7 % | 25.6 % | +124 m | Cat. 4 |
| km 3.2 | 0.4 km | 7.8 % | 8.9 % | +31 m | — |
Climb categories follow the road-cycling convention and rate the terrain itself (length and gradient) regardless of sport: Cat. 4 marks the easiest rated climbs, Cat. 1 the hardest, and HC (hors catégorie, “beyond categorization”) is reserved for the most brutal ascents. Short climbs below the Cat. 4 threshold stay unrated.
Almost everything on this loop is settled on the first climb. The flat opening out of the park invites a pace you cannot carry uphill, and arriving at the foot of the climb with your heart rate already high costs twice over on the steepest metres. Run the first kilometre easily and plan to power-hike the steep pitches briskly rather than grinding them at a shuffle.
At the top, get running again straight away: the descents here are long and runnable, and that is where sure-footed runners gain most. The short second rise is brief enough to take in rhythm.
The real trap is the way home. On tired legs and with the odd muddy patch, a fast descent becomes a fall risk precisely because the finish feels close. Keep your steps short and your eyes on the path.

Most runners will be out for 30 to 50 minutes. It is a short but uneven effort: rather than a steady pace, a long climb with surges into the anaerobic range alternates with quick descents where the legs work harder than the lungs.
The decisive section is the climb after the first kilometre. Prepare with hill repeats of three to eight minutes on steep ground, deliberately switching between strong hiking and running so the changeover comes naturally on race day.
The descents deserve as much attention. Run downhill on trails regularly, ideally straight after a hard hill session, so that technique and footing hold up on tired thighs.
The race is held in early September, and Lake District weather can turn at any time. Train in the trail shoes you will race in, on wet ground too, and remember that no drinks station is set out on this course: bring your own water or reusable cup.
