Ultra Trail Snowdonia isn’t a race you bluff your way through — it’s a race you prepare for properly. These UTS training plans are built for runners who know exactly what Eryri demands: steep climbs, long descents that batter the quads, rough ground that forces you to stay switched on, and weather that can turn a smooth day into a full mountain shift.
Across 15 or 20 weeks,this plan builds the specific fitness you need to move efficiently on technical terrain, handle sustained elevation, and stay mentally sharp deep into long efforts. You’ll develop climbing strength, durable downhill legs, and the endurance to keep pushing when the route feels endless. Sessions are structured around realistic UTS conditions: Broken rhythm climbs, long grinders, runnable but draining sections, and the fatigue you carry between big mountain days.
Expect purposeful mileage, back-to-backs, progressive elevation targets, and the right balance of strength and recovery so you can absorb the work without burning out. Whether your focus is finishing strong or pushing for a personal best, this plan gives you the structure to get mountain-ready, not just “run fit.”
By race day, you’ll know exactly how to pace the climbs, manage the descents, fuel through big hours, and keep moving when the terrain and weather start to bite.
Train specifically. Arrive prepared. Run UTS with confidence.

Ultra Trail Snowdonia is UTMB’s flagship mountain ultra in Eryri — a race defined by steep climbs, long technical descents, rough terrain and weather that can change the entire character of your day. It feels far closer to an alpine ultra than a traditional UK trail race, with big elevation, exposed sections, and long spells where you have to switch on and stay switched on.
If Lakeland rewards resilience, UTS rewards mountain competence: dealing with rough ground, changing conditions, and the cumulative toll of elevation hour after hour. It’s tough, honest, and hugely rewarding
