We’ve got one too. Have actually ridden it (kinda) in the dark but it’s better for fell running –
Aggies Staircase Fell Race
The race is held under FRA rules, race category BS.
From: Punstock Road, Darwen. GR689221
3.8 miles with 1150 feet of climb including three climbs of Darwen Moor. Starting at the top of Punstock Road, the route climbs a path then a track past Sniddle Hill Farm before crossing steep fields to join the main track up to Darwen Tower.
It then descends through the small quarry towards the top of Bold Venture Park, climbs steeply up a rough path known as Jacobs Ladder, heads across the moor and then down to the foot of Aggie’s Staircase.
