Cotswold Way Ultra Challenge.
The Cotswold Way Ultra Challenge sends you round a 100 km loop from Cirencester, on foot at whatever mix of walking, jogging and running suits you. Its character lies in a lopsided course: about two thirds of the climbing comes before km 53, and your preparation has to be built around that.
Cotswold Way Ultra Challenge 2027: Course, Elevation & Route Profile
The loop starts and finishes near Cirencester and reaches about 25 km to the west. Things stay calm until km 9, where a first short climb arrives. At km 23 comes the first long one, up to the day's high ground at just over 250 m, before the course drops back below 100 m. From km 33 the stretch that defines this challenge begins: one long climb, then three more packed close together, the last two at km 44 and 47. Short pitches there go beyond 20 percent.
Past the low point around km 56 the nature of the work changes. The climbs at km 57 and 67 are long but far gentler, averaging around five percent, and the last 30 km are only rolling ground between about 110 and 180 m. The organiser quotes around 2,250 m of ascent; measuring the course gives just over 1,800 m.
This is closer to a supported endurance day than a conventional race: a basecamp, stops with food and drink, medical and welfare cover, and a signed route on trails and footpaths. The half, quarter and three-quarter options use sections of the same loop, and the second half starts on the Sunday.
| Start | Length | Ø | Max. | Gain | Cat. |
|---|---|---|---|---|---|
| km 9 | 0.7 km | 8.4 % | 17.9 % | +61 m | — |
| km 23.3 | 1.7 km | 9 % | 17.1 % | +148 m | Cat. 4 |
| km 32.8 | 1.9 km | 8.2 % | 24.8 % | +152 m | Cat. 4 |
| km 40.7 | 0.7 km | 9.3 % | 23.8 % | +65 m | — |
| km 44.1 | 1.3 km | 9.7 % | 18.1 % | +127 m | Cat. 4 |
| km 47 | 1.7 km | 7.6 % | 18.4 % | +130 m | Cat. 4 |
| km 56.7 | 1.8 km | 5.9 % | 15.8 % | +109 m | Cat. 4 |
| km 67.1 | 2.5 km | 4.6 % | 11.9 % | +116 m | Cat. 4 |
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 Cotswold Way Ultra Challenge 2027.
Start under control
Do not split the 100 km into two equal halves. The first 53 km carry most of the climbing and should take clearly longer than the last 47. Decide beforehand that you will walk every climb from about eight percent, however strong you feel; that is not lost time, it pays for the closing hours.
Hold your rhythm
The day is decided between km 33 and 49. Four climbs sit close together there, at a point where only a third of the distance is done and your legs are still promising more than they can deliver. The descents between them are costly too: on the steep pieces you brake with the same quads you will need later.
Spend what is left
The main trap is someone else's pace. Because shorter options use sections of the same loop, you will be moving alongside people whose day ends soon. Stick to your own plan, and do not linger at the stops longer than you need to. If you stayed patient through the hills, the rolling finish from km 72 can still be run or walked briskly; that is where your reserve turns into time.
Training plan for Cotswold Way Ultra Challenge 2027: 12-week build
Build the base
If you run and walk the climbs you will be out for roughly 12 to 16 hours; walking the whole loop takes more like 20 to 28. Either way this is a low, even aerobic effort. What limits it is rarely your lungs but your muscles, your feet and your stomach.
Train race pace
The block of hills between km 33 and 49 is the test you are training for: several climbs in a row, most of them over 100 m, with three to six hours of movement already behind you. So build your long sessions with the climbing in the middle and more distance after it, which teaches you to find a steady stride again out of fatigue.
Rehearse the course
Two priorities carry the preparation. The first is time on your feet: long hikes with running mixed in, and long sessions on consecutive days, which build endurance at less cost than a single very long run. The second is strength and walking downhill, because the steep descents of the first half decide how much leg you have left for the rolling second. Brisk walking is also a skill that takes practice, especially for runners.
Arrive fresh
Since the course runs on trails and footpaths, your shoes and socks should have spent many hours on exactly that kind of ground beforehand. The event falls in mid-June, which puts the long block in spring. Practise eating real food in training, as you will at the stops, and find out what your stomach still accepts after ten hours. The signed route spares you the navigation, so all your energy can go into moving.
