Chester Ultra 50.
The Chester Ultra 50 is defined by its running order: over 50 miles around Ellesmere Port, more than 30 flat kilometres lead into the hills of the middle section, and then the course flattens out again to the finish. Preparing for this late February date mostly means being able to keep running once the last climb is behind you.
Chester Ultra 50 2027: Course, Elevation & Route Profile
The course is a loop that never gets high, topping out at about 140 metres. Its first third barely rises and stays below 40 metres, and more than half of the whole route is flat. As a trail ultra in late February, it asks for a build-up that falls almost entirely in winter.
The ground starts to lift from kilometre 33. Between kilometres 38 and 43 four short climbs follow one another, none longer than 700 metres, and together they reach the highest point of the loop. It stays rolling after that until the longest ascent at kilometre 53: just over a kilometre at nearly six percent.
The hardest moment comes late. At kilometre 59.5 the route climbs 900 metres at an average of eleven percent, around 100 metres of gain in one go, and a final ramp follows just before kilometre 62. From there the course gradually falls away. From kilometre 65 the remaining 15-plus kilometres are flat, exactly as the race began, only now with 65 kilometres in your legs.

| km 59.5 | 0.9 km | 11.1 % | 18.8 % | +100 m | Cat. 4 |
| km 62 | 0.6 km | 6.1 % | 10 % | +35 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.
How to pace Chester Ultra 50 2027.
Start under control
The flat first third is the real pacing problem. Nothing slows you down there, and every kilometre run too fast costs you twice: first on the climbs, then on the flat finish. Run this stretch at a pace that feels almost too easy, and eat to plan from the start, while your stomach still cooperates.
Hold your rhythm
The first group of hills from kilometre 38 is short enough to tempt you into running all of it. Hike the steeper pieces briskly instead, because the race is only decided between kilometres 53 and 62. The longest and the steepest climbs sit close together there, and the eleven percent ascent at kilometre 59.5 is a walk for nearly everyone. Plan it as one rather than trying to force it.
Spend what is left
The trap lies beyond it. After kilometre 65 no climb of note gives you an excuse to walk, and flat ground asks you to keep running without a break. Anyone who overspent in the hills loses more time here than they gained there.
Training plan for Chester Ultra 50 2027: 12-week build
Build the base
Age-group athletes spend roughly nine to 13 hours on these 50 miles. The effort is almost entirely steady aerobic work; the short climbs add spikes, but they shape the race less through their severity than through what they leave in your legs after many hours.
Train race pace
The key stretch runs from kilometre 53 to 62 and is followed by the flat finish. So you need to learn to climb after a long effort and then settle straight back into a running rhythm. Switching between a strong hike and a run is a skill in its own right, and it only comes with practice.
Rehearse the course
Build your long runs like the race: start flat, put the hills into the final third, then finish with one more flat stretch. Add sessions on steep ramps of around ten percent to work on powerful uphill hiking, and run the descent afterwards deliberately relaxed. Two longer days back to back prepare you better for the flat finish than a single extremely long run.
Arrive fresh
The late February date puts your biggest volume in the weeks around the turn of the year. Schedule the longest runs early and do part of them off-road, since this is a trail race. Use them to test food and kit in whatever winter conditions you have at home.
