The Durham Trail 10m is a ten-mile loop that starts in the city of Durham, follows the River Wear and the Dale Way, runs through the surrounding woods and comes back into the city to finish. The course rolls throughout, but three of its five climbs fall in the final four kilometres, and that is where the race is settled.
The first mile and a half is quiet, then two climbs lift you onto higher ground: a short one from 1.65 km and the longer one from 2.83 km, just over 600 metres with pitches above 15 percent. From there you run about six kilometres of rolling terrain some 60 metres above the start, before a steep drop shortly after the 9 km mark.
A flat stretch follows, and then the part runners remember. At 13 km comes the steepest climb of the day, 430 metres averaging nearly ten percent, and after a descent two more short, sharp ramps from 15.25 km and 15.9 km carry you almost to the line. Close to a third of the distance goes uphill, yet as a loop it finishes only slightly higher than it starts; the organiser puts the total climbing at 1,080 feet, about 330 metres.
The route is waymarked and marshalled, with electronic timing and two checkpoints offering water and sweets. Registration and race administration are based at the Graham Sports Centre at Maiden Castle, Durham University's sports site.

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 two early climbs arrive before you are properly warm, and the second, at over 600 metres, is long enough to punish a quick start. Take it at a pace you can keep running from at the top. The rolling middle section is where steady rhythm earns you time.
The steep drop after 9 km and the flat that follows invite you to push. That is the trap: from 13 km comes the steepest ramp on the course, and the last kilometre adds two more. Run out of legs there and you lose more in a few hundred metres than you banked on the flat.
So hold something back deliberately for the final four kilometres. For many runners, brief walking on the steepest part at 13 km is quicker than a forced jog, provided it leaves you able to work the descent and the two closing ramps.

Age-group runners will be out for roughly an hour and a half to two and a quarter hours. The effort is mostly aerobic, broken by short, steep climbs that push you over threshold. More than half the distance goes up or down, so there is no single steady pace to settle into.
The decisive stretch is the final four kilometres, where three climbs meet tired legs. Train for that directly: long runs that finish over short, steep hills, and hill repeats of 300 to 500 metres done after a steady run. The aim is to climb strongly an hour into the effort.
Downhill running matters just as much. The steep drop after 9 km and the descents between the closing climbs load the quads eccentrically, and if you are not used to that, you reach the last ramp on heavy legs. Build controlled descents into your hill sessions.
With the race in May, most of your build falls in winter and spring. Run on woodland paths and unsurfaced ground as often as you can, so your ankles and stride adapt to trail footing.
