The Seven Sins Run & Immortal Sinner.
The Seven Sins Challenge at The Seven Sins Run & Immortal Sinner opens the running year on New Year's Day near Yorkley with a loop that barely has a level stretch: five short, very steep ramps with descents just as steep between them. Getting round well is a matter of hill strength and controlled downhill running, not flat speed.
The Seven Sins Run & Immortal Sinner 2027: Course, Elevation & Route Profile
The loop starts and finishes at around 75 metres and is up and down from end to end. The longest climb begins just 400 metres in: almost a kilometre at roughly eleven percent, lifting you more than 100 metres to the course high point near 180 metres. From there the route drops back to the valley by kilometre 4, with one small rise on the way, before the second ramp, similar in length and steepness, climbs most of the way up again.
The second half comes in shorter bursts. At kilometre 6.4 sits the steepest section, half a kilometre averaging close to 14 percent with pitches above 20. A descent to the lowest point of the loop follows, then from kilometre 7.8 a longer climb of about 70 metres, and at kilometre 9.7 one last short wall before the course runs out towards the finish.
What defines the course is the balance of up and down: about a fifth of it is steep climbing, another fifth steep descending, and only around one metre in ten is level. With 435 metres of ascent in a little over eleven kilometres it is a hill race in the proper sense, and its 1 January date makes it the first race of the year. Runners who want more have the Immortal Sinner, at twice the distance.

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 The Seven Sins Run & Immortal Sinner.
Start under control
There is no pace on this loop you can hold for long. Budget the effort ramp by ramp: power-hike the steepest metres of the first two climbs rather than forcing a run, and take time back on the gentler ground at the top and bottom. Your heart rate can climb on the hills, but it has to settle again on the descent that follows.
Hold your rhythm
The race is decided over the last five kilometres. The steepest ramp, at kilometre 6.4, arrives once two long climbs and two steep descents have already tired your legs, and two more climbs come after it. Being able to keep running where others walk is worth minutes there.
Spend what is left
The biggest trap is the first climb. It starts almost straight from the line and is the longest of the loop, exactly where a crowded start pushes you up too fast. The second trap is the descents: braking hard all the way down them leaves your quads heavy for the late ramps.
Training plan for The Seven Sins Run & Immortal Sinner: 12-week build
Build the base
Expect roughly one to just under two hours of effort for the Seven Sins Challenge, depending on how much of the climbing you end up hiking. The work is never steady but a constant switch: short, hard spells near threshold on the ramps, broken up by steep descents where your muscles work eccentrically and your heart rate only partly recovers.
Train race pace
So train short, steep climbs specifically. Hill sprints and repeats of two to four minutes prepare you for the two long ramps, shorter and steeper efforts for the wall at kilometre 6.4. Practise switching between running and a strong power-hike as well, because on gradients above 20 percent fast walking is often the quicker choice.
Rehearse the course
Downhill running matters just as much. Put steep descents into your runs and take them deliberately relaxed, with short, quick steps. Strength work for quads and calves, such as lunges and step-ups, makes your legs more resilient to the pounding of five descents.
Arrive fresh
With the race on 1 January, your build-up falls in December. Plan the key sessions around the holidays so the last hard week of hill work does not slip, and keep the final days before the start easy.
