The Dragonfly Challenge at Pooley Country Park sets a clock rather than a distance: you get six hours and decide for yourself how many laps to fill them with. A single lap counts as a race, and so does a marathon or far more, which is why preparing for it starts with choosing what the day is meant to be.
There is only one course: a closed lap of 3.3 miles, just over five kilometres. Everything else follows from the lap count. One gets you slightly more than a 5k. Four make a half marathon, eight a marathon, and within the time window more than 50 miles are possible.
The first two kilometres are close to level, dipping and rising by only a few metres. Then comes the only real climb: the way up to the 50-foot Golden Tower of Leaves. It gains a little over ten metres in about 300 metres, short and moderate, and marks roughly the middle of the lap. The drop on the other side is just as quick, and the second half then echoes the gentle ups and downs of the first. That adds up to around 30 metres of ascent per lap.
Underfoot, open grassland alternates with parkland paths, and that mix rather than the terrain is what makes this a trail race. It takes place on a Thursday in May, with an aid station as part of the event. The real character of the format lies in repetition: run a marathon here and you stand at the foot of the same climb eight times.
| Start | Length | Ø | Max. | Gain | Cat. |
|---|---|---|---|---|---|
| km 2.2 | 0.3 km | 3.9 % | 5.2 % | +12 m | — |
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.
What you are dividing up here is a time window, not a distance. Fix your lap target before the start and work backwards: a marathon allows an average of 45 minutes per lap, stops at the aid station included, which leaves plenty of room. Aiming for 50 miles is another matter, at 16 laps in under 23 minutes each, for the full duration. Your target lap is the most useful tool of the day, more so than any per-kilometre split.
The climb to the tower decides nothing through its severity, only through its frequency. On lap one it costs almost nothing; on lap eight you will notice it. So take it deliberately easy from the start. If you plan walking breaks anyway, this is the natural place for them, because the descent follows at once and gives you your rhythm back.
The trap is the flatness. On a lap this easy to run, the early circuits feel too slow and you are tempted to bank time. You pay for that cushion in the final two hours, when every new lap becomes a decision about whether to run another one. So eat and drink by lap count, not by feel.

How long you are out there is up to you. On this lap, many age-group runners will need around two to three hours for a half marathon and four to six for a marathon. Whichever target you pick, the effort stays almost entirely aerobic and steady. The short climb to the tower adds only a small stimulus and does not call for hard intervals.
The laps that matter are the late ones, when that same small rise arrives on tired legs and carrying on becomes a mental task. Prepare with long runs matched in duration to your lap target. Where you can, run them as a loop of about five kilometres that keeps passing your own supplies. That rehearses exactly what race day asks of you: heading out again while the end of each lap invites you to stop.
Build a short rise of about 300 metres into that loop and run it at the same calm effort every time, including the downhill behind it. This trains the discipline the climb demands. If your target is a long one, practise a planned mix of running and walking in these sessions, so that it does not first appear in the race as a result of exhaustion.
Because the lap mixes open grassland with parkland paths, take part of your long runs onto grass rather than staying on tarmac. Use them to test shoes as well as the food you intend to take by lap count. With the race in May, your longest sessions fall in the spring weeks before it.
