The 20-mile race at The North Coast Race crosses Jersey’s north coast from east to west, from St Catherine’s almost at sea level to Les Landes. No single hill settles this one. The sum does: more than 1,000 metres of climbing on rugged coastal path calls for a build-up that makes constant up and down feel routine.
The start at St Catherine’s sits just above sea level, and the first 15 kilometres are the most restless. The path swings between about 20 and 90 metres, dropping right down and climbing back out again and again. A steep step at kilometre 6 is only the opener: kilometre 8 brings the longest climb of the day, a little over a kilometre with ramps above 20 percent, and kilometre 13.5 a shorter one that averages double figures.
After that the course runs higher and calmer. At kilometre 17 you reach Les Fontaines, where the 10-mile race starts, and from there both races share the line. One deep cut remains: just past kilometre 23 the path falls to around 20 metres and rises straight back above 70, again with pitches beyond 20 percent. The finish at Les Landes sits at about 80 metres.
The surface sets the character. These are genuine coastal trails with long rugged passages and technical sections, and only about an eighth of the distance is flat. Aid comes at two points, Bouley Bay and Devil’s Hole.

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.
Think of the race in two parts, split at kilometre 15. The front holds the hardest climbs, the back holds the longer distance, and whatever you overspend early is missed twice over later. Hike the steep ramps from the start, even when that still feels unnecessary in the opening kilometres. On paths like these, running a slope costs a lot of strength and buys little time.
The race is decided between kilometre 17 and the finish. The cut at kilometre 23 is the test: if you top out and can break straight back into a run, your plan has worked and the last ten kilometres, with their smaller waves, stay runnable. If you are reduced to a walk here, this stretch costs more time than any climb before it.
The real trap is the downhill. Around 40 percent of the course descends, a good third of that steeply, and on rugged ground fresh legs invite a speed your quads will not repay later. Ease off on the descents in the first half, and carry enough food and drink yourself for the long stretches around the two aid points.

Expect somewhere around four to six and a half hours, depending on fitness and footing. This is no steady long run: short steep climbs, steep descents and a few runnable passages trade places, so a long aerobic effort is shot through with brief hard spikes you cannot sit out.
The skill that matters shows up after three hours or more: hiking a short steep climb briskly and breaking back into a run at the top without a pause. Train that exact transition. Build sets of two to five minutes of steep hiking into your long runs, each followed straight away by running, and place them deliberately in the second half of the session so they land on tired legs.
Downhill running matters just as much. The many steep drops load the quads harder than the climbs do, so schedule regular sessions with longer descents on uneven ground, plus strength work for legs and core. Choose stony, broken paths for the long runs where you can: forest-road mileage does little for the technical sections, and hours of watching your footing tire you just as the climbing does.
The 1 May date puts the build-up across winter and spring, so plan the longest sessions for the weeks before it. Use them to test your vest and fuelling too, because with only two stations you carry a good part of your supplies yourself over 20 miles.
