Course, checkpoints and support
The route links a range of local trails and canals, including the Sandstone Trail, the Marches Way beside the River Dee, Helsby Hill, Frodsham, Beeston Castle, Delamere Forest, the Bridgewater Canal, the Shropshire Canal, the Trans-Pennine Trail and the North Cheshire Way. There are 12 checkpoints along the course. Checkpoint provisions include drinks (water, cola, tailwind, juice), snacks, fruit, sandwiches and hot food; pasta and soup are provided at specified village hall checkpoints. A medic is available.
A single dropbag is permitted at the Frodsham location (used for both CP6 and CP11). One pacer is allowed from the halfway point at Frodsham Parish Hall; the pacer must be on foot, self-sufficient and carry the mandatory kit. Due to parking limits, support crew access is restricted at some checkpoints and dogs (except service dogs) are not permitted at checkpoints or at the start/finish venue.
