MANDATORY KIT
Each participant must carry with them all the items listed in the mandatory kit checklist and take all the clothing and equipment with them during the race.
There will be randomised checks at the start line. A penalty up to disqualification will be applied to participants who do not have any of the individual mandatory kit items with them when inspected.
Due to the long duration of the event, participants should ensure their electronic devices last throughout by planning for sufficient battery life, such as using charge-on-the-go options or carrying spare batteries.
