Yr Wyddfa (Snowdon), is the highest mountain in Eryri (Snowdonia), and also the whole of England and Wales. It peaks at an impressive 1,085 m (3,560 feet).
Starting and finishing at the foot of this iconic mountain, you will be challenged as an individual, or part of a team, to ascend and descend Yr Wyddfa as many times as possible in 24 hours.
Categories for solo runners, pair relay and team (up to 5) relay. Pair and team entries receive one timing chip, meaning only one person will be running at one time.
Being UTMB Indexed, this is also a great qualifying or preparation race for UTMB Mont Blanc. The individual challenges mean that there is a 50K, 100K and 100m mile UTMB indexed challenge.
There are no aid stations out on the course. The following are available for participants:
The challenge is to complete as many ascents and descents of Yr Wyddfa (Snowdon) as possible within the 24-hour period. The race winners will be the athletes who complete as many of these as possible.
If a runner begins a lap but does not complete it within the 24-hour period, it will NOT count towards the total for that runner or team. In the event of a tiebreak on the number of ascents and descents, the fastest will win!
Mandatory to enter the UTMB Mont-Blanc lottery, a valid UTMB Index is achieved by completing at least one race of the UTMB World Series or a UTMB Index race in the relevant category within the previous 24 months.
