This is a 5km with a difference – the route includes the Guinness World Record ’World’s Steepest Street’!

Steepest Street Run

The 322-metre long Ffordd Pen Llech has a maximum gradient of 37.45% and is ready to be tackled just after the start of the run. Once you’ve reached the top of Harlech with views out to the sea you can let momentum take over as you head back down through the town and past the historic castle to the finish line.
