Pool Swim - 400m

Route Description

Your swim takes place in the leisure centre pool, making it exceptionally accessible for beginner triathletes. With three to a lane and marshals counting your lengths, it's head down and get swimming!

Once you have completed your swim it's in to transition and on to the bike. Exiting transition and shooting out towards Ynys on the flat and fast coast road, you turn up towards the Castle and enter the closed road section of this exciting route. Pushing your legs to the max as you climb the hill towards Harlech, you can try and admire the impressive view, or just wait until you reach the turn-around point and watch it all rush by on the way back down. It's a simple out and back route and you will soon be back in transition ready for the run.

In the shadow of the castle, the run takes you across the beautiful dunes and along the Harlech beach. Once off the beach and running through the lower Harlech streets you are now in full view of the piece de resistance; your final challenge is to run up the 108 steps and Storm The Castle!
