Snowdon Mountain Railway Station (map)
One of the toughest half marathons in the UK and now the decider of the 2025 Trail Half Marathon World Championship. This iconic course takes on over 1,192m of ascent across 21K, most of which is up Wales’ highest peak - Yr Wyddfa (Snowdon). The views are as stunning as the trails are challenging, with those returning fastest in their age division awarded the title of 2025 XTERRA Trail Half Marathon World Champion.

All XTERRA Trail Run World Championship (TRWC) competitors are welcome to attend this informative session.
All competitors must attend the compulsory safety briefing in the start area on race day 15 minutes before your race start time.
Remember the Ultra Trail Marathon, Full Trail Marathon, the Half Trail Marathon and the 10K Trail Race take place in a mountainous environment, and at times you will be in remote areas.
Furthermore, there will be rough technical sections in some areas. Therefore, you must be vigilant at all times. In the spirit of trail running, please keep a lookout for your fellow competitors.
Half Marathon, Marathon, and Ultra distances must be prepared to carry the mandatory kit detailed in the Pre-Race Info section
The race is run on public footpaths, please be aware of, and be considerate to, other people enjoying the beautiful Eryri scenery. Keep left at all times.
All four routes run on the roads through Llanberis at the start.
You must exercise caution when crossing roads.
The 10km route includes a variety of trail, grass track, and a small amount of tarmac.
The Full and Ultra Marathons run along the A4085 for about 1.5 miles (2.4km). Please be aware of traffic and exercise caution. Run on the right-hand side of the road.
The Full and Ultra Marathons will cross through Beddgelert on the road. Please be aware of traffic.
The Full and Ultra Marathons will cross the A498. Please exercise caution and be aware of traffic.
There is a road crossing for all distances over the A4086 near the Victoria Hotel in Llanberis. Please exercise caution and be aware of traffic.
All four of the routes will run on the roads near the Llanberis Slate Museum. Please exercise caution and be aware of traffic.
The Ultra, Full and Half Marathon routes will climb the slopes of Yr Wyddfa (Snowdon) (Marathon and Ultra on the PyG track, Half Marathon on the Ranger path). This is a mountainous environment and can be particularly slippery in inclement weather. Please remain vigilant at all times.
The Ultra and Full Marathon climbs the PyG Track on the slopes of Yr Wyddfa. YOU MUST NOT veer on to Crib Goch at Bwlch y Moch.
The descent from the slopes of Yr Wyddfa is fast. Be respectful and aware of other users on the mountain. Also, take care on rocky sections particularly if it is wet.
If you pull out of the race you must report to Race HQ or call 07527 034 308 quoting your race number.
We can pick you up at the nearest feed station and transport you back to Llanberis and the race start/finish area. Please be patient; we will recover you as quickly as possible.
If you decide to pull out whilst off road you must make your way to the nearest feed station. Please note this may be behind you.
This is a cupless event, there are no plastic or paper cups on the course. If you can, please bring your own collapsible race cup to carry during your race. Otherwise we will supply one to you free of charge at Number Collection.
In the interest of competitor safety, as with all events, it might be necessary to implement contingencies on the race. We will do all that we can to ensure you have the best experience and will only make changes to the race if it is absolutely necessary. Thank you for your understanding.
