The Solstice Social is not a race but a social run on a 50k loop around Exeter, devised by local runner Andrew Iley. You set off from a car park early in the morning and reach a ridgetop park around sunset. The preparation that matters is for the climbing, which only starts to count once you are past 30 km.
It begins at Trood Road car park, and the loop gives away its height straight away: from 67 metres it drops almost to sea level in little more than a kilometre and stays low for a while. The first gradients arrive at 6 km and 12 km, the second of them noticeably stiffer. That one carries on up to just over 140 metres before the route falls away again and runs mostly low and rolling between 18 km and 30 km.
The core of the day sits in the final third. At 31 km the longest climb starts, gaining 143 metres in 1.7 km and touching almost 15 percent at its steepest. A second, gentler ascent then leads to the high point of the loop at 231 metres, just short of 35 km. Once the long descent is done, three more ramps wait from 43 km onwards, and the last of them only begins half a kilometre from the finish in the ridgetop park.
What shapes the day, though, is the format rather than the elevation. Ruby Red Running hosts this Christmas run just ahead of the winter solstice, free to enter and limited to 30 places. Donations go to the My Name'5 Doddie Foundation, an MND charity. You can run as much or as little of the loop as you like.

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.
There is no placing to defend here, so daylight sets the rhythm: your window runs from the morning start to sunset. Just under a third of the route is flat and only about a tenth is steep, which means the cost comes from the length. Keep the flat and gently rolling stretches relaxed and walk the ramps from the outset, including the early ones you could still run while fresh.
The stretch that decides your day runs from 31 km to the high point. Almost 200 metres of gain are packed into a few kilometres, and you meet them with 30 km in your legs. March the steep parts without forcing it so you can still run at the top, because the descent that follows asks for alert quads.
The trap is the social setting itself. Chatting along, the low first half feels easier than it is, and matching someone else's pace there gets paid back on the three ramps after 43 km, when the light is already going. If the day turns against you, cutting it short is no defeat: the format explicitly allows running only part of the route.

Allow something like six to nine hours for the full loop, depending on your pace and how much you walk. That makes it a calm aerobic effort broken up by many short steep sections, which lift your heart rate briefly but call for no hard intervals. The main stimulus you need is time on your feet rather than speed.
The real demand sits in the last third: gradients of almost 15 percent with 30 km already behind you, then three further ramps in the final seven kilometres. So move the climbing in your long runs towards the end of the session. A hilly final hour prepares you far better than the same hills straight after your warm-up.
Practise switching between a brisk uphill march and easy running over the crest as well. Add downhill running on tired legs, because after the high point you lose well over 100 metres within a few kilometres, and your quads still have the rest of the day to get through.
Conditions follow from the date: December, a very short day and an arrival around sunset. Put your longest sessions in the short days leading up to it, run part of them into dusk, and test a head torch and clothing that work from morning through to evening. Train yourself to eat regularly over many hours too, wearing the pack you intend to carry on the day.
