What's involved

These races have been designed to be as safe as possible, without reducing the scale of the challenge. After all, these are tough events which you've knowingly signed up for! Please understand that participation in this event is a serious undertaking and carries risk.

The Rab 14 Peaks Ultra™ and Rab Snowdon SkyRace® routes were designed to offer a real test of mountain running, speed, endurance and technical ability on a truly uncompromising course, designed to challenge skyrunners of all abilities. These are truly world-class SkyRace routes!

The routes feature sustained sections of scrambling at Grade 1 difficulty. Specifically, these are Tryfan North Ridge (SkyRace only) and Crib Goch (west-bound traverse). You are advised to research what constitutes ‘Grade 1’ difficulty, as well as the nature of the scrambles present on this route, well ahead of the event.

In addition to the above, there are lengthy sections of highly technical terrain that all participants must negotiate, where use of hands may be required by less technically confident runners. Most of the route is very rough underfoot with long sections of rocky terrain, which can be very slippery underfoot if wet.

The entire race route is subject to potentially severe weather, typical of the mountainous areas within this region of Eryri/Snowdonia. For this reason, competitors must be confident in their ability to complete the route within the Checkpoint cut-offs, in all but the most adverse weather conditions. Bad weather routes may be enforced.

Required experience

For an event of this nature, real mountain running experience and ability is more relevant than race results. It is expected that you arrive on the start line well trained, physically and mentally and confident in your ability to safely complete the race within the time limit.

These are not events for trail-running novices.

A grand tour of some of the UK’s most scenic trails, ridges and scrambles, it's certain to become an international Skyrunning classic!

This route gets straight to the action early on! Starting with ascending the famous Rhyd-Ddu path, before heading east to top out across the epic Y Lliwedd ridge, then taking a technical descent down to the shores of Llyn Llydaw before a 4x4 track to Pen-y-Pass, where the first Aid Station awaits. A steep ascent to the challenging terrain of the Glyders is next, before plunging down the technical Y Gribin ridge to the Ogwen Valley, where Aid Station 2 greets runners.

There is little respite as the course heads south to ascend the stunning Tryfan North Ridge Grade 1 scramble, weaving its way upwards through rocky outcrops and gullies and passing the famous cannon stone on route to the summit. Technical, rocky and undulating trails guide runners back to Pen-y-Gwryd Aid Station 3, then you’re ready to finish the western loop of this figure-of-eight route. After a west-bound traverse of the iconic Crib Goch Grade 1 scramble, the stunning Snowdon Ranger Path descent awaits, offering runners a fast and rocky quad-bashing descent home to Rhyd-Ddu.

With a course designed by a Race Director who knows how to create incredible, uncompromised race routes, the Snowdon SkyRace® will be sure test the full capacity of any skyrunner’s ability!

I have done Glen Coe Skyline twice and while I don’t doubt that Curved Ridge and Aonach Eagach provide exposure and challenges, what is between is very much boggy fell running. Not here in Wales, the route is relentless, technical and hard. Tryfan and then the climb to Crib Goch and the traverse are just so special. This is an epic route, it will become a classic. It’s now the UK’s best race!

What a course! From start to finish it had it all, a true mountain athletes dream!! This technical, tough and stunning route really should be celebrated. The same way Trofeo Kima, Zegama attracts us brits overseas to experience different cultures and trails, the Snowdon SkyRace and its special course should do the same for top athletes in Europe. I hope they come to experience our weather, culture and unique mountains! 2019 Skyrunner UK and Ireland series overall and Snowdon Skyline champion Damian Gielty

If you come from a climbing background this race will suit you big time. But do not underestimate thigh-trashing long runnable descent to the end! This year wet weather made it even more spicier and kept me on my toes. Thanks to generous amounts of free coffee!" 2019 Skyrunner UK and Ireland series overall champion Kasia Osipowicz

You know you are doing an epic race when so much of it is spent climbing and scrambling past Welsh mountain goats! Montane athlete Jayson Cavill

What an epic race!! I love technical races and this one was glorious - with massive ascents and just as massive descents, I loved the route! The race support and organsiation was just as wonderful - so slick and well done - I cant wait to do it again next year! Professional mountain guide and 2019 third lady Alice Kerr

Brutal but beautiful route! Well marked course, very well organised! Cool event T-shirt with a nice beer and food at the end. I will be back! 2019 competitor Simon Roberts

Wow! Everything a sky running race should be. A brilliant route with relentless climbs, exposed scrambles and heaps of technical running. This race was well organised with a great support team on route. I met up with old friends and made lots of new friends out on the course. What a fantastic way to spend a Sunday! 2019 competitor Shan Jones
