Centurion South Downs Way 50.
The Centurion South Downs Way 50 goes from Worthing to Eastbourne, around 80 kilometres in one line and mostly on trail. It never gets high, but three times it drops almost to sea level and climbs straight back onto the Downs. Preparing for it means preparing for those late climbs, not only for the distance.
Centurion South Downs Way 50 2027: Course, Elevation & Route Profile
This course only knows one direction: it starts in Worthing, ends in Eastbourne and never returns to the start. About 85 percent is trail, the rest road. The first six miles are the approach to Chanctonbury Ring, and that stretch already climbs twice: right after the start, then from km 8 up to around 220 metres, close to the highest ground of the whole day. From there you stay on the South Downs Way.
The middle swings between ridge and valley floor. Just before km 19 you are practically at sea level, and the longest climb of the race takes you some 200 metres back up. Around km 36 the path then holds above 200 metres for several kilometres before sinking to about 50 metres by km 45.
From there the character changes. The longer climbs of the first half ran at four to just over six percent; the four in the second half all sit around eight. Twice more the route falls almost to sea level, near km 55 and near km 67, and each time it goes straight back up. The last climb comes from km 73. After that only a descent and flat closing kilometres into Eastbourne remain.

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 Centurion South Downs Way 50.
Start under control
Only about a twelfth of this course is steep uphill, which tempts you to run nearly all of it. Take the climbs of the first 30 kilometres at a brisk hike anyway, including the harmless one right after the start. The seven aid stations divide the line into eight sections: count from one to the next, because no lap will bring you back past the start.
Hold your rhythm
The day is decided between km 55 and km 75. The last three climbs each begin low down and together add around 450 metres, on legs with more than a marathon in them. Your speed on the hill matters less there than whether you can start running again at the top. After the first of them the path barely loses height until about km 63, and that stretch pays out every reserve you saved.
Spend what is left
The trap is the long descents. Between km 10 and km 18 you lose over 200 metres, and letting that roll freely takes the quads you need later, because this course goes down as much as it goes up. Control your speed early and your legs will still carry you through the flat closing kilometres at a run.
Training plan for Centurion South Downs Way 50: 12-week build
Build the base
Most age-group athletes need roughly nine to twelve hours, and with a 13-hour limit there is little slack at the back of the field. The effort is almost entirely aerobic but never uniform: hiking uphill, running the ridges and braking downhill take turns, broken by short hard minutes on the steep pitches.
Train race pace
Because the ramps of the second half are steeper than those of the first, your vertical belongs at the end of your long runs. Finish hours in with two or three climbs of about two kilometres, as close to eight percent as your terrain allows. Practise the moment at the top as deliberately as the climb itself: from the hike straight back into a run, with no pause.
Rehearse the course
The second focus is downhill running, since around 1,800 metres of descent load the quads at least as hard as the way up. Repeated controlled descents and strength work such as lunges and step-ups prepare you for it. Start early, because the muscles need weeks to adapt to this load.
Arrive fresh
The 10 April date puts your longest runs between January and March. Do most of them on trail, like the race, and set some up point to point, carrying what you need between two aid stations. Eat and drink at a hike on the climbs, so that it still works six hours into race day.
