Locally Sourced Slate Coaster
With a 37.45% maximum gradient Ffordd Pen Llech in Harlech shot to fame when it 'stole' the title of 'World's Steepest Street' from Baldwin Street in New Zealand. Yes, they then 'stole' it back again, but as they don't have a race up it you'll still be running in the 'World's Steepest Street Run'!
