Crew rules
One crew vehicle per runner, up to a long wheel base transit van; no motorhomes. The vehicle must display the crew pass (handed out at registration) to enter any crew location. Crews may meet runners only at the listed crew points; being crewed anywhere else risks a one hour penalty, disqualification or a ban. Cut-offs apply only at aid stations. centurionrunning.com
Pacer rules
Pacers are allowed from the Kithurst Hill crew point. On foot only, one pacer with the runner at a time, with several pacers allowed over the last 50 miles. Pacers wear a pacer bib from registration and pass it on at handovers. The finishing lap of the track may be shared with friends and family. centurionrunning.com
Drop bag rules
Drop bags go to Washington, Housedean Farm and the finish, one bag per aid station, deposited at the start on Friday evening or Saturday morning. Maximum 50cm x 30cm x 30cm, labelled with name, aid station and race number. Finish bags go straight to the finish. Collect at the finish from 0800 to 1230 on Sunday; anything left is disposed of. centurionrunning.com
Cutoff philosophy
Runners must finish within a 30 hour limit. There are cut offs at every aid station on the route, set to keep runners on course to finish within the overall time limit. centurionrunning.com
