Over the full ultra distance, the Humanity Direct Tring Trail Challenge is a race of two halves: you share the route with the Half Ultra as far as km 24, then turn away a few kilometres short of the finish and head back up into the Chilterns. That turn shapes your preparation more than the total climbing does.
Start and finish are at Tring Cricket Club in Beechwood, on the London Road. The first ten kilometres are close to level and even drift slightly downhill, to around 120 metres. The longest climb of the day begins at km 10.5 and gains a little over 110 metres in two kilometres. After that you stay high: the course rolls up to just over 270 metres at km 16 and holds its height for a long while before dropping quickly back to the valley from km 22.
The routes part at km 24. The Half Ultra runs out its last three kilometres, while you leave that line with about half the day still ahead. Nothing from here matches the first climb for length, but there are plenty of short ones: from km 28 the course steps up to around 230 metres, then rolls between 180 and 205 metres. Near km 44 it falls away clearly for the last time.
At km 45 you rejoin the line you left at km 24 and run the flat closing stretch to the cricket club. This is a one-day trail challenge raising funds for Humanity Direct. The route is marked, four checkpoints with food and water divide the day, and transport to and from Tring station is part of the arrangements.

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 ten kilometres take almost no effort and are still the most expensive of the day. Half Ultra runners use this same flat line too, and they can afford a very different pace. Do not measure yourself against them; run so that the first climb changes nothing about your plan, and walk its steep parts from the start.
The day is decided between km 24 and km 36. You arrive off a descent, the finish is close, and you are running away from it. From km 28 comes the steepest sustained piece of the second half, nearly a kilometre averaging six percent. Plan this phase to be slow, and take what you need calmly at the checkpoints.
The trap lies just after that. The many short waves from km 37 look harmless but break any rhythm you have. Mix walking and running early there instead of forcing every crest. If your quads have survived to km 44, you can use the last descent and actually run the flat kilometres home.

Age-group runners can expect to be out for roughly 5:30 to 8 hours. The effort stays almost entirely aerobic, but in the second half short climbs interrupt it again and again. A little over 40 percent of the course is flat, which means you have to be able to jog calmly after hours on your feet, not just hike.
The key session recreates the turn. Plan long runs so they pass your car or your front door and then carry on for another two hours. That prepares your legs and your head for the moment at km 24 when stopping feels closest.
On the hills you need many short efforts rather than long ascents. Choose rolling ground for long runs, with ramps of half a kilometre to two kilometres, and put the densest run of hills into the second half of the session. Practise switching between brisk walking and running, and run some descents deliberately tired, because the drop near km 44 lands on quads that have already done a lot of work.
A mid-September date puts your longest sessions in summer, so schedule them early enough. Four checkpoints with food and water mean long stretches between stops: use training to learn what you can eat and what you want to carry yourself. This is a day on marked trails, so at least part of your long running belongs off road.
