Although largely a trail event, due to the nature of the event, there are inevitably some road crossings where it will be necessary to slow and possibly stop. No roads are closed en route. Particular attention should be given at these points.

As always, if you see a runner experiencing difficulties please inform Checkpoint Marshals. Each runner should have the Race Organiser’s mobile number. Our team will always endeavour to reach any participant in difficulty but due to inaccessibility of the Trail this can take time. 

The trail runs close by to Water Courses like the River Dee and Shropshire Canal – care should be taken at these areas, particularly given the time of the year of the event.

Conditions might well be muddy and icy, be careful and mindful, of uneven and slippery terrain, falling branches, some overgrowth, stiles to negotiate and close to the stiles, barbed wire.  There might also be some danger presented by steep drops, close to cliff edges at Helsby & Frodsham Hill (runners aren’t beside the cliff).  Watch your footing.  Also be mindful and respectful of other users of the trail, giving priority to others.

Additional Support Crew Access Points you might find helpful, nearby to where runners cross.

8 Miles – Please do not park at CP2 as there is no parking available.  Please use local Pay & Display parking at Saddlery Way Car Park, 5 Saddlery Way, Chester, CH1 4LZ a short walk away.

12.9 Miles – Checkpoint 3 – Waverton Village Hall or beside the canal on Eggbridge Lane.

19 Miles – Shady Oak Restaurant, Bate’s Mill Lane, Tarporley, CW6 9UE – Runners pass along the canal.

26 Miles – Gresty’s Waste Car Park, Chester Road, Delamere, Tarporley, CW6 0SP – Please note this is a very busy road crossing for runners here so please avoid distracting runners as they cross and preferably support at the checkpoint nearby.

28 Miles – Checkpoint 5 – Delamere Forest.

38 Miles – The White Lion, Manley Road, Frodsham, WA6 9DD. Runners pass close by along the North Cheshire Way (a short walk away)..

Please note, due to parking limitations, No Support Crews Permitted at the following locations:

Checkpoint 1 (Stoak)
Checkpoint 4 (Crib Lane)
Checkpoint 6 (Frodsham)
Checkpoint 7 (Alvanley)

Please also do not park directly at Checkpoint 2 and use the pay and display car park detailed above.

Support Crews risk disqualification of their runner if they are present at any of the above locations where we have stated No Support Crews Permitted. Further details are contained in the specific section for Support Crews which will be sent out in your race instructions.

During the race

Please inform a GB Ultras Race Marshal at one of the Checkpoint’s or Race HQ.  This will ensure all participants who are registered and pull out of the race are accounted for, allowing for the accurate and safe running of the event.  If a participant withdraws at a Checkpoint they must hand over their Race Number & GPS Tracker to the Event team to signal their retirement.  Marshals will inform the race organiser and each of the remaining Checkpoints can update their event documentation.

Upon withdrawal from the race, it is the responsibility of the individual to get themselves home (or to the finish if required to collect their dropbag). We would recommend having your own Support Crew or someone on standby to collect you in case of unexpected withdrawal during the event.

Where possible, runners withdrawing from the race may be able to be transported by GB Ultras event support from a checkpoint back to Race HQ however this cannot be guaranteed. Priority will be given to runners still participating in the race.

Where it is possible to transport a runner to the finish, this will only be available after a checkpoint closes and therefore may involve a significant wait. In addition, as event teams are deployed to multiple checkpoint locations, transport to Race HQ may involve intermediate stops on route for further (potentially lengthy) periods of time before heading to Race HQ.

GB Ultras also reserve the right to pull any participant out of the race on health grounds.
