The Hardmoors 26.2: White Horse carries the marathon distance in its name, but its long course measures 29 miles, close to 47 kilometres. Not until kilometre 21 does the loop from the Sutton Bank Visitor Centre show what it is about: three big climbs, the last of them on the way home. Preparing for it means preparing for the second half.
Start and finish are at the Sutton Bank Visitor Centre near Thirsk in North Yorkshire, at about 300 metres. The first six kilometres undulate around that level before a climb of just over two kilometres takes you onto the highest ground of the day. You stay up there between 350 and 390 metres until around kilometre 13, then give back almost 250 metres by kilometre 20.
The core of the race starts at kilometre 21: two kilometres averaging nearly ten percent, with ramps to 17, lifting you almost 200 metres. After the next long descent, the second big climb arrives at kilometre 29 with 137 metres over 1.6 kilometres. The loop then falls to its lowest point at kilometre 37, a little over 80 metres above sea level. Ten kilometres remain from there, climbing almost without pause from kilometre 39 and costing more than 200 metres back to the finish.
The race belongs to the Hardmoors 26.2 series and runs through moorland. It is a small, amateur event with clear rules: mandatory kit, 500 ml of drink carried on you, no cups. You print your own map and route description.

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 are the kindest of the day: rolling ground, one longer climb at kilometre 6, then the long way down. That is exactly where the trap sits. Bank time on this descent and you reach the foot of the hardest section on tired quads. Run it so that kilometre 20 feels too easy.
For most runners the climb at kilometre 21 is a hike. Switch early to a brisk, even stride instead of forcing the first steep metres, and only start running again at the top once your breathing has settled. The same applies at kilometre 29, except that your legs now have two long descents in them.
The race is decided from kilometre 37. With the lowest point of the loop behind you, the entire way back up to the visitor centre still lies ahead, and being able to run rather than only walk here gains more time than anywhere else. So drink regularly from the start from what you carry: a mistake from the first half shows up on this run home at the latest.

Mid-pack runners are out for five to seven hours. This is above all a long aerobic effort, but not a steady one: the steep climbs drive your heart rate up even at a walk, and the descents between them work the legs rather than rest them.
The phases that decide the race come late: the one-two between kilometres 21 and 31 and the return to 300 metres from kilometre 39. Both demand strong climbing after hours on your feet. In between you need quads that can absorb several kilometres of braking downhill without taking it out of the next ascent.
So put the elevation of your long runs towards the end and finish them on a climb whenever you can. Practise brisk uphill hiking on gradients of 10 to 15 percent as a session of its own, because that is how you will spend much of the hours that matter here. Longer descents belong in the plan regularly, so race day is not the first time your muscles brake for this long.
A race date in early May puts the longest sessions in late winter and early spring. Run them in the kit you will wear on the day, including 500 ml of drink, so weight and fit hold no surprises. Work through the printed route description beforehand too, and take map and text on long runs: finding your way confidently five hours in is a skill you can practise.
