If you see a runner experiencing difficulties during the Chester Ultra 100 please inform Checkpoint Marshals. Each runner should have RACE HQ mobile numbers stored in their phone (shared in the Race Instructions email in the weeks prior to the event).

It is the role of the entrant to be self-sufficient. Should an incident occur, our team will endeavour to reach any participant in difficulty as quickly as possible, with Event staff stationed in hard to reach locations. Phones must be used only in an emergency to conserve battery power should the need arise.

Participants who lose time helping another fallen participant, can claim this time back, subject to RD discretion and under the proviso of completing within RD agreed conditions. Please note any extended time will be ‘within’ the cut-offs of the event, due to event staffing, medical cover and venue hire.

GB Race Tracker provide the Live Online GPS Tracking for the event with updates on participant positions approximately every 2 minutes (subject to signal). On the front of each tracker is an SOS button which when pressed immediately alerts the Race Director & Race HQ that urgent help is required who can then act accordingly.

In the event of a Medical Emergency please call 999 and then inform Race HQ.

In an Emergency where there is a risk to life or limb, please follow these instructions:

1. Please use your foil blanket/thermal bag and use any warm clothing that you are carrying.
2. Trigger the SOS button on your tracker by holding the button on the front of the tracker down gently for 3 seconds
3. In an Emergency call 999 and ask for an Ambulance
4. Call Race HQ and inform the team of the Emergency – we may have a medical team close by.
