Chester Ultra 50 : 27 February 2027
The Chester Ultra 50 is a 50 mile trail ultramarathon around Chester organised by GB Ultras. The course records 849 m of ascent, has a field limit of 750 places and the 2027 edition is sold out. The event is licensed by the Trail Running Association and is held under UK Athletics rules; it also awards ITRA and UTMB mountain performance index points.
The route is well waymarked and links canal towpath with inland trails, passing through Delamere Forest, the Sandstone Trail, Helsby Hill, Frodsham and sections of the North Cheshire Way. The race uses live GPS tracking and provides seven checkpoints along the course; Checkpoint 1 is water only and other checkpoints provide food and drinks with vegetarian and vegan options. Some checkpoint locations restrict supporter and crew access for safety.
Entrants must be at least 20 years old, in good health and have completed an organised marathon distance prior to race day. No pacers or support runners are permitted and no dropbags are allowed; participants must carry all items they need in addition to mandatory kit.
Mandatory kit must be carried at all times and includes a waterproof coat with sealed seams, a long sleeved base layer, a minimum 1 litre water container, a foil blanket, a headtorch and a secondary torch, a whistle and a fully charged mobile phone in waterproof covering. The event provides GPX files and online race tracking for navigation and monitoring. Visit the organization's website for the most recent information.
