Route Description

The Snowman Legend Bike route is famous for being one of the best triathlon cycle routes in the World. A single loop, it takes in many of North Wales' most iconic mountain passes and routes and is a challenge in its own right. Start with the climb up to the famous Pen y Pass; the gateway to Snowdon. Mountains tower all around you with views all the way to Anglesey as you flow down into Llanberis and on 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 mountain 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 - but not before you have run 12km out and back down the stunning Nant Ffrancon Valley with the formidable rocky ridge of Tryfan looking down on you. Don't let this relatively flat section lull you into a false sense of security, Moel Siabod, the highest peak in the Moelwynion mountain range is waiting for you. Legend athletes must ascend up beautiful, but gruelling rocky paths for 3.5km before reaching the summit at 872m above sea level. Here you will turn around and run back down again. To get to the 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 Snowdon awaits.
