Choice of three circular routes of 16 (2,800 feet of ascent), 26 (3,200 feet of ascent) and 36 miles (6,200 feet of ascent). All are circular, running westerly towards the Lancashire border. All routes split at the Lumbutts checkpoint and participants can (if they wish to) change route here by informing a checkpoint marshal. The 16 mile route returns to the start from Lumbutts on a fairly direct route incorporating Stoodley Pike. The information on the routes can be found at https://calderdalehike.org.uk/route/ and a map showing all the routes in relation to each other can be found at https://calderdalehike.org.uk/wp-content/uploads/2021/09/CalderdaleHike2022AllRoutes.pdf
