Gear Check – What You Need to Know
Gear check is the designated area where you can safely leave items you won’t take on the course. Key rules:
• Only official race-issued bags are allowed.
• Your bag must be labeled with your individual tag (red, blue, or orange – depending on your assigned corral).
• Gear check operates from 5:30 to 7:20 AM.
• You can retrieve your items until 4:00 PM.
• Do not leave valuables – the organizer is not responsible for lost items.
Gear check zones are color-coded and assigned to specific start corrals (A–K). Make sure to drop your bag in the correct location.
