All teams must carry at least two mobile phones as it allows walk officials to call you if you are overdue at a checkpoint and find you if you are lost or in need of help.

You need to give us your mobile numbers at checking in when you arrive.

Please don’t give us other family member’s mobile numbers as they may get worried if we give them a call to find out if you are lost and where you are!

Teams using mobile phones for support or assistance from team supporters will be disqualified.
