Introduction

The Snowman Standard Distance Triathlon takes the traditional Olympic format and elevates it—literally.

Swim in the shadow of Yr Wyddfa (Snowdon), tackle a stunning (and serious) bike course through Eryri’s rugged mountain roads, and finish with a trail run that includes demanding climbs and rewarding views. This is a challenge that will test your strength, strategy, and grit, all set in the awe-inspiring beauty of Snowdonia National Park. If you’re looking for a triathlon that goes beyond the ordinary, this is it.

Description

Begin with a swim in the freshwaters of Llynnau Mymbyr under the watchful eye of Yr Wyddfa (Snowdon). Exit the water and cross the wooden footbridge for the first time into transition.

The Snowman Bike route is famous for being one of the best triathlon cycle routes in the World. It takes in most of North Wales' most iconic climbs and routes and is a challenge in its own right. Starting close to the base of Yr Wyddfa, flow down the Nant Gwynant Pass and towards Beddgelert. Here you will meet the Glaslyn river cycling alongside the whitewater rapids. Heading over to Maentwrog along the narrow, winding ascents and descents you will then start your climb to Tan y Grisiau, Blaenau Ffestiniog and on up the Crimea pass. The equally steep descent flows down through Dolwyddelan and along the Lledr Valley to Betws Y Coed. From here, you’re almost back, but you must make the climb up to Capel Curig and the Plas Y Brenin outdoor centre before you reach transition.

There is a reason that the Snowman Triathlon regularly gets called the toughest multi-terrain triathlon in the UK. That’s because to complete this race you must first summit a mountain; Moel Siabod, the highest peak in the Moelwynion mountain range. Ascend up 3.5km of beautiful rocky paths before reaching the summit at 872m above sea level and turning round to run back down again. To finish, you must turn right and run through the forest, then back along the fire road towards the lake. The finish line framing Wales' most famous peak, Yr Wyddfa awaits.

Cut off time

In the interest of athlete safety and the safety of our volunteers on the course, there will be strict cut-off times in place.

  • You have a total of 55 minutes to complete your swim and exit transition.
  • You have a total of 4 hours and 25 minutes to complete your bike and exit transition.
  • You have a total of 3 hours to complete your run.

4 steps to wellbeing
Sleep well

A good night's sleep is an essential foundation for a healthy lifestyle, effective training and weight control.

Train slow

Low-intensity training is easier for you, reduces the risk of injury and helps builds an efficient aerobic system.

Eat natural

Cut out sugar & junk food, reduce carbs, eat natural foods and train your body to burn fat for fuel.

Get outdoors

Fresh air, natural light and reconnecting with nature all help to improve mental and physical wellbeing.
