The Scafell Pike Sea to Summit runs from the beachfront at Seascale to the top of Scafell Pike and back to the sea. Your preparation comes down to one stretch above all: just over four kilometres averaging 20 percent, which only begins once more than 20 kilometres are already in your legs.
The start is on the beachfront at Seascale, effectively at sea level, and the mountain takes its time to arrive. Up to kilometre 22 you gain almost no height: a single climb of about a kilometre near kilometre 10 lifts the course to just under 80 metres, and from there it stays around 70.
At kilometre 22.7 the race changes character. The next 4.4 kilometres stack up nearly 900 metres of ascent, more than half the day's total, with sections beyond 30 percent. Reaching about 950 metres does not end it: after a short dip, a second push from kilometre 28 packs almost 150 metres of climbing into just 600 metres of ground. The course then falls to roughly 350 metres by kilometre 32, where a third hard climb asks for another 300.
From kilometre 37 it is almost all downhill, you are back at about 40 metres by kilometre 42, and the final eleven kilometres stay low all the way to Seascale. What sets this race apart is that span within one day: sea, summit, sea, on foot and under your own power. The whole route is waymarked with orange arrows, pit stops break up the distance, and professional mountain safety staff support the race.

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.
Around two thirds of the distance sits below 100 metres, yet that is not where the race is settled. The first 22 kilometres only determine what legs you bring to the mountain. Run them easily enough to feel underused, and eat regularly there, because that gets much harder on a 20 percent slope.
The race is decided between kilometres 23 and 34, where over 1,300 metres of ascent sit in three blocks. Hike the steep sections at a brisk, even stride and judge your effort by your breathing rather than your speed: pace per kilometre means nothing here. The high ground is not the end of the work, since the climb from kilometre 32 meets you with whatever you left unspent.
The biggest trap is the descent. You drop roughly 600 metres in little more than three kilometres, and letting it run costs you twice: on the third climb, and over the last eleven low kilometres, where easy running only pays if your quads are still there.

Expect somewhere around seven to eleven hours, depending on your fitness. The effort stays aerobic but comes in two kinds: long steady running at low altitude, with a middle section of steep hiking and hard descending that loads the muscles quite differently from the kilometres before it. Mileage on the flat alone gets you to the mountain with nothing trained that you need there.
The core of your preparation is therefore steep uphill hiking on tired legs. Build long runs so the climbing arrives after two to three hours rather than at the start, because that is how this race is built. Add weekly sessions of 20 to 40 minutes of very steep climbing; without a steep hill, stairs or a treadmill at full incline will do.
Your quads need as much attention for the way down. Introduce steep downhill repeats early and gradually, since the soreness lingers for days at first. Finish some long sessions with flat kilometres after the descent: the last eleven of the race demand exactly that, relaxed running on legs that have just done over 1,600 metres of climbing.
With the race in early September, your main block falls in the summer months. Use it to test shoes, pack and fuelling on at least one mountain day of six hours or more. Practise being quick and purposeful at a pit stop too, since lost minutes add up over a day this long.
