Mandatory gears

You must carry your own Mandatory Gear at all times during the event. Random gear checks will be performed during the event. 

For the sake of fairness to all runners, a 30 minute time penalty will apply for every item that is missing. 

For on-course gear checks, this time penalty will be served at the location of the gear check so a runner will not be able to proceed on course until the time penalty is served. 

During this time, the runner must arrange for the missing item(s) to be replaced or they will not be allowed to continue on course even after the time penalty has been served. 

For severe breeches of mandatory gear or failure to comply with the requests of event marshals, the runner may be disqualified. 

Where it is not feasible to serve a time penalty on course, the time penalty will be added to the runner’s overall race time. The breech will also be listed within the results spreadsheet.
