Maverick Adidas Terrex X & Snowdonia routes

Reputedly Maverick's toughest event of the season, this day is one of much anticipation for trail running aficionados. As such, Maverick have refreshed all their routes in anticipation for this years event.

The Ultra 50km course will climb Mt Snowdon, while the other three routes take runner up the Llanberis Path. All races will then wind their way along the river before a tough ascent of the mammoth Moel Hebog - the towering 782m peak - and then down toward Beddgelert Forest. The race will culminate with one last climb up Moel Eilio.

Although good weather can never be guaranteed in Snowdonia, the spectacular natures of the trail routes can be.

Ultra cut-off times are detailed below:

0900 - Start at Parc Padarn
1200 - Checkpoint 1, Nantgwynant

Parc Padarn

Team Entry: Teams will consist of 4 members, with each member being assigned a specific race. In the end, the team with the quickest cumulative time across the 4 different routes will win. Runners kick off together, before veering off down whichever race you have chosen to tackle.

    Got to be one of the ultimate UK events to do. Stunning scenery and a great route. Just when you think you are done you go up again. Take food and a coat. 👍

    Did the Middle in 2016

    This is the perfect event for those wanting to move from UK trail running into slightly tougher and even more incredible running views. With the different distance options you can run in this amazing place but at the right level for you, then go back the next year and go even further!
  • Did the Long in 2018

    This is my favourite trail running event, without exception. Maverick have absolutely nailed the best route with exceptional marking and aid stations. I will keep coming back to this race every year and no one does it better than Maverick!

    best route I have run ever, cannot wait to return in 2020, so well organised, not sure if any other event in the uk trail scene can match it.
  • Did the Long in 2018

    I did the snowdon marathon This was my first maverick race and wasn’t disappointed the organisation was first rate, support at the aid stations was great I did the marathon route with my two dogs and they were also well looked after at the aid stations I can’t wait to do it again this year with my dogs.

    Did the Ultra in 2018

    This was the best Trail Marathon I've ever run. The landscape and scenery speak for themsleves but the route was superb with some brutal climbs 'after' summiting Snowdon. The organisation was faultless and freindly and the course markings were the best I've seen for any race. A truly great event.

    Did the Ultra in 2018

    My first big trip into the high mountains running. Quite simply stunning. Cracking start straight to the top for a warm up, magic descents on gnarly trails back down to the lake and continuous beautiful scenery around the foot of the Mountain and just when you think that's it I have had it, another epic rise and miles of wonderful decent to the finish. Great atmosphere, superb feed stations - all you'll ever need to support you through the Mountains. Epic.

    Did the Middle in 2018

    Great fun and really relaxed vibe. They were happy for me to change distance on the day without any hassle. Beer at the end and a fantastic cake and biscuit stall - what’s not to love!

    Did the Long in 2018

    I can't rate it highly enough. The course is stunning and although tough, it's achievable to all who dedicates some time to training. The official photos are amazing (capture you in some breathtaking backdrops) and are free to download. Never had such in-depth conversations with strangers whilst running, you can tell everyone is there for the same thing...the love of the outdoors!
