Thetford Festival of Running.
The Thetford Festival of Running is a 5.4 km February loop in Thetford Forest, 99 percent of it off-road. With no real climb to speak of, this short trail race is settled by the pace you can sustain on that ground from the first stride to the last, not by anything a hill does to you.
Thetford Festival of Running 2027: Course, Route Profile & Map
The race is based at High Lodge in Thetford Forest, near Brandon. The loop returns to where it began, and almost all of it is trail rather than road underfoot. Anyone coming from tarmac should not picture a road race with an off-road stretch: this is a forest race from end to end, held in the middle of winter.
The first 700 metres or so fall gently before the course climbs back to start height by 1.25 km. A second dip follows just short of 2 km, the middle of the lap is a slight up and down with no clear direction, and the lowest point does not come until 3.6 km.
From there the path rises almost without interruption to 5 km, returning you to the height of the start, and the last 400 metres run level to the finish. Only about 14 metres separate the highest and lowest points, and nothing is steep. What stands out in that closing phase is not its gradient but its length: no other part of the loop holds one direction for as long.
| Start | Length | Ø | Max. | Gain | Cat. |
|---|
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.
How to pace Thetford Festival of Running.
Start under control
With so little height difference, the course sets no rhythm for you, so you have to set it yourself. Spread the effort evenly and take the small undulations of the first four kilometres without letting your breathing change much. Your watch helps less than usual, because a 5K time from the road does not transfer directly to trail. Run on feel rather than on a target pace borrowed from tarmac.
Hold your rhythm
The trap comes right at the start. The gently falling first 700 metres feel like a gift and invite a speed you cannot hold afterwards. The bill does not arrive at once; it arrives on the long closing section.
Spend what is left
That is where the race is decided, between 3.6 and 5 km. The rise is barely visible, but it does not let up, and it comes when your legs are already tired. Consciously lift your effort at the low point to hold your pace, and keep the final kick for the level last 400 metres.
Training plan for Thetford Festival of Running: 12-week build
Build the base
Expect to be out for roughly 25 to 40 minutes, depending on your form. That is a sustained hard effort just under or at threshold, with no hills to interrupt or divide it. What counts is the ability to hold a high pace for a long time, not the strength for individual climbs.
Train race pace
So build your training around tempo runs of 15 to 25 minutes, lifting the pace slightly towards the end. That mirrors the job from 3.6 km onward: when it gets hard, you have to raise your effort, not merely maintain it. Where you can, finish these sessions on a gentle, even rise. Steep hill sprints do little for this race, while longer intervals around threshold do a great deal.
Rehearse the course
Because nearly the whole course is off-road, at least one fast session a week belongs on unsurfaced paths. It teaches you what race effort feels like there, so that on the day you are not relying on a pace that only holds on tarmac.
Arrive fresh
The race falls on 21 February, so your preparation sits entirely in winter. Schedule your key sessions for December and January, and use that time to try out shoes and clothing off-road, so that nothing is new on race day.
