Ultra Trail Snowdonia 2024: Races, start times and live tracking for UTMB blockbuster

One of the hardest races in the UTMB circuit is back this weekend. Taking place in the Snowdonia National Park, Ultra-Trail Snowdonia (UTS) promises steep climbs, technical terrain, and hopefully, breathtaking views. 

Last year, the weather was uncharacteristically warm. For some runners, it was a little too hot, with very little shelter on route causing many people to overheat.

This year, the weather is looking fairly warm again, with temperatures reaching 20°C, although light – we hope – rain threatens across the weekend. But mountains can be unpredictable, and anything can happen during the hours the runners are out on the course. In 2022, the 100m race was actually cancelled midway, due to severe weather.

Races and start times

UTS 100m kicks off 13:00 (local time) on Friday May 10
UTS 100k has an early start of 05:00 on Saturday May 11
UTS 50k follows a few hours later at 08:00 on Saturday May 11
ERYRI 25k begins at 10:00 on Saturday May 11

“I’m feeling weirdly relaxed but excited about it, which tells me I’m as ready as I could be.”

Charlotte Clarke

Ultrarunner Charlotte Clarke will be among the many eager competitors toeing the line at the start of the 100km race this weekend. She’s only ever broken the 100km mark once, in 2021, when she raced the Salomon Serpent Trail. Clarke says it is a ‘stark contrast to what’s to come’. 

“I am excited. I feel like I’ve been in a real pursuit of finding out what I’m capable of and this might really show me. I’m feeling weirdly relaxed but excited about it, which tells me I’m as ready as I could be.”

After completing the 100k last year, Christian Quick is back to tackle the 50km course: “I did the 100k last year with the idea of doing the 100m this year but after the brutal heat of 2023, I decided to go for a distance I’d find more enjoyable. It’s a taxing course, and I have Lakeland 100 and UTMB OCC coming up later in the year, so the plan is to go out and have fun.”

Lorna Mann of Run Dem Crew, is taking on the 25k. While the shorter of the races, it’s by no means a walk in the park, with over 1300m elevation: “As a slower runner, I find the cut offs times a little intimidating. I’ve recce’d the route and done as much hill training as possible – so I’m ready. But those trails are pretty gnarly!”
