Entrants must be at least 20 years old on race day and must have previously completed an organised ultramarathon of at least 50 miles. A single pacer is permitted from the halfway point (Frodsham Parish Hall) onwards. Support crews are welcome at most checkpoints, but are not permitted at Checkpoints 7, 10, and 12 due to parking and safety restrictions.
