Forty miles without a single course marker: at the Bowland Ultra & Trail Half, the long race is a January day of finding your own way out of Slaidburn and back, over shooting tracks, technical singletrack, road and bog. Nearly 2,000 metres of climbing make it hard; navigating on tired legs is what sets it apart.
Slaidburn is both start and finish, with one big loop and no laps in between. The first 15 km are a run-up: two moderate climbs from km 3 and km 6 lift you to just over 400 m, then the course rolls back down. Then comes the first wall, more than 200 m of gain in little over a kilometre, with ramps beyond 20 percent.
The middle of the race holds the highest ground. From km 23 the course climbs to over 430 m, and from km 31 comes the longest ascent of the day. It starts in the valley at around 160 m and only ends close to 500 m, the highest point of the route. From there the route drops in one go and stays low for around 20 km, broken only by a short climb at km 46. From km 58 there is one more wall of about 200 m before the way down to Slaidburn, the last stretch on the way you came out.
The race takes its character from the ground underfoot and the absence of any marking. Shooting tracks alternate with technical singletrack, road and bog, and the route is adjusted where stiles are broken, new hedges appear or footpaths on the ground differ from those on the map. Four fully equipped aid stations break up the day: Whittendale Farm and the village halls at Bleasdale, Chipping and Dunsop Bridge.
| Start | Length | Ø | Max. | Gain | Cat. |

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.
More than a quarter of this route is steep and only about an eighth is flat, so kilometre splits tell you little. Pace by effort and walk the steepest ramps briskly from the start. That applies above all to the wall around km 15, which arrives while the race still feels easy. Run it and you pay for it later.
The day is decided between km 31 and km 35. This ascent leads to the highest point and comes just as you reach halfway. Climb it so that you can still break into a jog at the top, because the low kilometres before the last climb are the one part of the course where real time can be made. If you can only walk there, you lose more than any climb has cost you.
The real trap is fatigue combined with a course that has no markers. One missed turn costs more than any pacing decision, and concentration fades as the hours add up. Keep aid station stops short: in wind, rain or frost you cool down quickly when standing still, and your rhythm is slow to return afterwards.

Expect roughly nine to 13 hours for the 65 km, depending on ground and weather. The effort is mostly aerobic, but it is repeatedly broken by steep ramps that spike your heart rate and by long descents that tire the quads more than the climbing does.
Two phases separate well-prepared starters from the rest: the long ascent between km 31 and km 35, and the closing wall from km 58, which arrives when little strength is left. So build long runs that put their climbing in the second half, and finish them with a steep ascent at a brisk walk. Steep downhill work on tired legs belongs in the plan as well, because the course gives back every metre it climbs.
The ground needs sessions of its own. Run long on soft, uneven terrain regularly, on bog where you can, so that your ankles and hips know the change from singletrack to road. The organiser warns of rain, ice, snow, high winds and frost. A race on 9 January puts your build in the same season: test clothing and fuelling on long runs in exactly that weather.
Practise navigating too. Do several long sessions on unfamiliar, unmarked paths following the route on your watch, until checking it on the move becomes routine. Download the latest route file before the race and make sure your watch battery lasts the whole day.
