The Shropshire Hills 50 Ultra Challenge is new to the calendar, and its longest loop heads south-west from Craven Arms towards Knighton on the Welsh border before returning through historic villages. The two biggest climbs are done by kilometre 20, so your preparation has to cover a steep first half and a long second one.
The base is the Shropshire Hills Discovery Centre in Craven Arms. After two and a half flat kilometres the loop makes its first climb, up to around 280 metres, then drops back to about 140. It stays nearly level until kilometre 11, and then comes the section that defines this course: from kilometre 13 a steep climb of just over two kilometres. After an intermediate descent, the hardest stretch of the day starts at kilometre 17.5, almost two and a half kilometres at an average of just over ten percent. The top, a little above 420 metres, is the highest point.
The route stays high until kilometre 25, then falls in one go to below 180 metres. Around 15 almost level kilometres follow with only one small rise before the last long climb starts at kilometre 42: 2.6 kilometres, steady rather than steep, up to around 270 metres. One last rise shortly before the end climbs to a little over 220 metres, and then the loop runs out.
The arc gives the day its character: out towards the Welsh border, back through historic villages, fully signed and with GPS tracking. The first rest stop comes around ten kilometres after the start, the other two at kilometres 26.5 and 41.5. Alongside snacks and drinks, this distance includes a picnic lunch.

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.
More than half the climbing falls in the first 25 kilometres, yet more than half the distance is still to come after that. So run the first half by effort rather than pace, and keep the level stretch before kilometre 11 deliberately easy: it is the run-up to the hardest part, not a chance to bank time.
The day is decided between kilometres 13 and 20. Walk the steep sections without hesitation and carry enough: the first two rest stops are a little over 16 kilometres apart, and exactly that stretch holds both big climbs.
The real trap comes afterwards. The fast descent after kilometre 25 and the level kilometres behind it invite you to win back lost time. Push there and you reach the last long climb at kilometre 42 on empty legs. The third rest stop sits right at its foot: eat there before the climb starts, and on the flat hold a pace you can still carry to the finish.

Age-group athletes need roughly six and a half to ten hours for the 55 kilometres. That is mainly aerobic endurance work, but not an even kind: the steep stretches demand strong walking, the flat sections between them a calm, economical running pace. Train only one of the two and you pay for it in the other.
What decides the day is the pair of long climbs before halfway and then, after hours on level ground, the climb at kilometre 42. The first block asks for strength, the second for the ability to switch back into climbing mode late on. So build your long runs with the ascent early, flat kilometres after it and one more climb at the end.
Steep uphill walking deserves its own session, for instance repeats of 15 to 20 minutes on a steep ramp, because that is about how long the hardest climb of the course lasts. Train downhill running too: the long descent after kilometre 25 hits tired quads, and almost 30 kilometres still lie beyond it.
The challenge falls in mid-September, which puts your long sessions in the summer. Run them on trails rather than tarmac and practise eating as you go, since the rest stops can be more than 15 kilometres apart. Test as well how you get back into running after a solid meal like the picnic.
