The longest distance at the QE Country Park Trail Run covers 21.6 km of ancient woodland and tree-lined gravel tracks in Queen Elizabeth Country Park, Horndean. The loop falls back almost to start level three times and keeps its steepest climbing for after kilometre 14, so preparing for this race mostly means preparing for its final third.
Start and finish sit at around 117 metres, and the ground tilts upward at once: a steady kilometre and a half, then a shorter pitch at kilometre 2 that reaches almost 190 metres. By kilometre 5.5 the course has handed all of it back. The middle section earns the height again in stages, first with a kilometre of climbing, then from kilometre 9.8 with two ramps in close succession, the first averaging almost eight percent. They top out near 200 metres before the third long drop.
The race is decided between kilometres 13 and 16. Out of the last dip come three climbs with barely a pause: the second is only 450 metres long but averages close to ten percent, and the third adds almost 60 metres of height in 750 metres, lifting you to around 233 metres. The course stays rolling at that level until kilometre 18, then falls to the finish in two steps, split by a small rise at kilometre 20.
The park itself sets the character. Tree-lined gravel tracks alternate with trails beneath the trees of ancient woodland, so one loop takes you across several surfaces. The race is timed, more than 1,000 runners are expected across the three distances, and the 21.6 km goes off first.

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.
Only about a tenth of this course is flat; the rest is going up or coming down. A target kilometre split is no use here, so steer by effort. Until kilometre 13 the climbs mostly run at four to five percent and stay runnable, with the ramp from kilometre 9.8 the one exception. Take them all at a level where you don't need the top to get your breath back.
The trap lies in the descents before the closing section. From kilometre 11.6 you lose around 75 metres in little more than a kilometre, and the temptation to let go is strong. Every hard landing there gets billed shortly afterwards on the steepest ground of the day.
From kilometre 14.7, only 300 metres separate the two steep ramps, which peak close to 17 percent. A brisk hike there is often as fast as a strained run and far cheaper. What counts is running again the moment it levels off: if you still have rhythm on the rolling stretch to kilometre 18, the last three kilometres of downhill give you the time others leave on the course.

Expect roughly 2:15 to 3:00 hours depending on fitness. The effort is mostly aerobic but never steady: eight climbs keep adding short spikes, and between them the quads work on the way down. A road half marathon is therefore the wrong model, not least because the course runs a little past the classic 21.1 km.
Everything comes down to whether you can still work uphill on steep ground after 14 km. Build long runs so that the hilliest part comes at the end, not the start. Two ramps of 300 to 700 metres, repeated several times after ninety minutes on your feet, match the closing section better than any interval session on fresh legs. Use them to practise the switch from hiking back to running as the climb eases.
Controlled downhill running on tired legs matters just as much. The course falls nearly as far as it rises, and three longer descents come before the hardest part. Put regular downhill stretches into the second half of your long sessions and keep your stride and posture tidy rather than simply braking.
A late-January date places the whole build-up in the winter months. Even so, move as many long runs as you can onto gravel and woodland paths, because the change of surfaces is part of this race and cannot be practised on tarmac. The water points on course are refill stations, so try out beforehand how you drink and top up over this distance without losing your rhythm.
