Route description
Route description

This route will begin at the base of the striking Harlech Castle. Immediately after the first bend runners will find themselves looking up toward Ffordd Pen Llech - crowned the 'World's Steepest Street' in 2019.

With a maximum gradient of 37.5% and a total climb of 50 metres across the 322 metre street, this is certainly a challenge to be reckoned with. Once you've reached the top, athletes will be greeted with panoramic views over the sea, before heading back down through Harlech and over the finish line.

The hard work will all be worth it for the epic race village which will host food and drink, massages, a shop, and plenty more.
