The Rab Helvellyn Sky Ultra links five Lake District ridge-lines into one circuit from Patterdale, with Striding Edge, Swirral Edge and Long Stile Edge along the way. Rock matters more to your preparation than distance: almost none of this course is flat, and going down asks as much of you as going up.
Start and finish share the King George Playing Field in Patterdale in the Ullswater Valley, and between them the circuit runs anti-clockwise through high ground. Underfoot you get paths, trails and rock, and the way leads past Helvellyn and Red Tarn, Fairfield and Cofa Pike, Hart Crag, Dove Crag, Red Screes, High Street. Depending on how it is measured the total comes to between 3,500 and 3,700 metres of ascent, and only about a twentieth of the course is flat.
From kilometre 4 the first long climb leaves the valley, 3.5 kilometres at around 14 percent. The route then stays high for a long time, with short, very steep pitches near kilometres 13 and 17, before falling for seven kilometres to the valley floor.
Kilometre 27 opens the longest climb of the day, a little over five kilometres and nearly 700 metres of gain. Two more rises follow between kilometres 35 and 39, then the course drops deep again. From kilometre 45 the last two climbs stack up to around 500 metres, and nine kilometres of descent lead back to Patterdale. The race director may still amend the line, so check it before you start.

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.
Split the day at the low point near kilometre 26 and treat it as two races. By then the first long climb and the high ridges are behind you, yet more than half the ascent is still to come. Hike the steep ground from the outset, even if your legs offer more in the early morning: about a third of the course climbs steeply, and running it buys you little.
The race is decided between kilometres 27 and 33. Straight out of that long descent you climb nearly 700 metres again, with four more climbs waiting afterwards. If you can keep moving steadily here without stopping, you have the hardest part under control.
The trap is the descending. Almost half the course falls, much of it steeply and over rock, and chasing time there wrecks your quads for the double climb from kilometre 45. Ration your food as well: only one station is fully supplied, alongside two support points in the valley.

Expect something like 10 to 15 hours depending on your form, with an early morning start. It is a long aerobic effort but not a steady run: steep hiking and concentrated descending alternate all day, and the spikes come from short pitches rather than from speed. Flat kilometres do little for you here, because almost nothing on this course resembles them.
The decisive skill is climbing steeply straight after a long descent. Build your long sessions so a big climb follows an extended descent, and put the hardest hill in the middle third of the session. Two long mountain days back to back also prepare you for the double climb from kilometre 45, which arrives after more than 40 kilometres of work.
The core of the plan is steep power hiking and downhill work under fatigue, since the eccentric load here runs for hours. Run regularly on rocky, technical ground until you can read your footing ahead on descents without losing speed. Forest paths cannot teach that, so plan mountain weekends on real rock.
The 17 July date puts your long mountain days in May and June. Use those sessions to practise eating too: the early start with a breakfast that suits you, and longer stretches carrying your own food, since only one station is fully supplied.
