Event overview

The Craft Snowman forms part of a popular multi-activity event weekend encompassing all that the adventure playground of North Wales offers and is infamous for a reason - just when you think you’re done there is a different challenge you’re not expecting.

An exciting, adrenaline-fuelled and truly epic and unforgettable experience; completing The Snowman is a tick that every triathlete wants.

Are you up for the trio? The Snowman is also the second part of a prestigious Adventure Series of triathlons and duathlons.

If you prefer the single disciplines, dive into the Snowman Swim or a pure trail/sky run over the distance of your choice. Whichever you enter, the vibe is sure to exceed any expectations.

It’s a perfect introduction to trail running and could serve well as a lovely double day if combined with the Snowman Swims or even help you to stay loose for the Triathlon/Duathlon the following day.

What a race this was. Firstly for the physical effort, secondly for the scenery and lastly for the organisation... All the marshalls were excellent and the organisation was great. Hoping to do the series next year. Thanks for a great weekend. Luke C

What a day of racing, this is an amazing race, so full of sights, sounds and fantastic support. Chris K

What can I say, well - in a nutshell AMAZING, 10/10 on everything, but be warned if you don't train for this event it will destroy you. This is an amazing triathlon. I cannot recommend enough... brilliantly organised, thoroughly marshalled and signed. Chris K
