The 50-mile Calderdale Way Ultra is a loop from Heptonstall that only reaches its lowest point at the canal in Brighouse, then turns back over the moors. Its steepest climb is saved for kilometre 71, and that is what your preparation has to answer: steep ground with more than 70 kilometres already in your legs.
From the start in Heptonstall the course heads towards Hardcastle Crags, dropping first and then turning steeply uphill from kilometre 2: a little over 200 metres of gain in just over two kilometres, with pitches above 25 percent. You then cross Upper Calderdale from Midgley Moor and climb towards Wainstalls. This northern section belongs to the long course alone, and it holds two more short climbs at kilometres 11 and 19, both averaging above ten percent.
Around kilometre 33 you reach the canal at Brighouse, down at just under 60 metres. From here you share the line of the 30-mile race, over Norland Moor and along the Calderdale Way back to Heptonstall. That swing defines the day: moor tops and a canal on the valley floor belong to the same course, and everything you ran down has to be climbed again. The race is open to all, printed maps are handed out at registration, and cut-offs apply along the way.
The decision comes late. At kilometre 67 there are some 120 metres to gain at ten percent, and after another long descent the key climb arrives at kilometre 71: nearly 200 metres in a kilometre and a half, touching almost 25 percent at its worst. After that the route stays near 300 metres for a long way and only falls towards Heptonstall at the very end.
| Start | Length | Ø | Max. | Gain | Cat. |
|---|---|---|---|---|---|
| km 1.7 | 2.2 km | 9.9 % | 26.5 % | +213 m | Cat. 3 |
| km 10.9 | 1.2 km | 11.7 % | 24.1 % | +144 m | Cat. 4 |
| km 18.9 | 0.9 km | 10.9 % | 21.6 % | +92 m | Cat. 4 |
| km 35.5 | 2.1 km | 6.7 % | 15.6 % | +141 m | Cat. 4 |
| km 51.6 | 1.6 km | 8.6 % | 16 % | +140 m | Cat. 4 |
| km 57.9 | 1.6 km | 7.3 % | 13.4 % | +118 m | Cat. 4 |
| km 66.6 | 1.3 km | 10 % | 17.4 % | +128 m | Cat. 4 |
| km 70.6 | 1.5 km | 13.2 % | 24.6 % | +198 m | Cat. 3 |
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.
The first 20 kilometres demand discipline because your legs are still fresh. Running three steep ramps at that stage spends something you will miss after kilometre 60. Hike them from the outset and treat the northern section as the journey to the real race.
The biggest trap is the way down to Brighouse. The gradient invites you to let go, and quads spent there are paid for over the 46 kilometres that follow. Reach the canal feeling as though you have barely started. The bag drop at CP5 exists on this course only, so decide beforehand what you need from it and keep the stop short.
The race is settled between kilometres 67 and 72. Both climbs begin after descents, so your legs enter the slope already tired from braking. Leave ambition aside here and hold an even step, because a little over eight kilometres with hardly any climbing wait at the top. Anyone still able to shuffle then gains more than those who fought for places earlier.

Age-group runners will be out for roughly 11 to 16 hours on this loop, with around 2,400 metres of climbing. It is not a steady effort: the day breaks into hiking on steep slopes and running in between, all aerobic but with the muscular work changing constantly.
What matters is what happens after the canal. The two key climbs sit beyond kilometre 65, a distance many runners never reach in training. So load your long runs at the back: put the climbs in the final two hours rather than at the start. Weekends with two long sessions back to back mirror the second half better than one very long run.
Practise steep hiking on purpose, on slopes above ten percent, at a step you can hold for a quarter of an hour. Downhill running matters at least as much: more than 40 percent of the distance descends, and every descent here ends at the foot of the next slope. Eccentric strength in quads and calves is what carries you through the last 20 kilometres.
With the start on 1 May, your longest block falls in the months before it. Take the map and your food on those long runs: read the route while tired, eat to a plan rather than by feel, and rehearse once what belongs in the bag drop.
