FAQs

Where should racers be from 7:45 am until the start of the race?

All racers should wait at the Swim Start for race instructions.

Which direction does the bike race follow?

After the swimmers leave the water and enter the transition area, bikers will travel through the VIP Parking lot, up the hill (Cantera Way) to Point San Pedro Road, turn right at the top of the hill, follow the road until the turn around point (Back Ranch Meadows Campground Entrance), return on the same road, pass the entrance to McNear’s Beach, and follow Point San Pedro Road until the turn around point (at the quarry).

Are there any Transition Area rules?

Yes. To enter the Transition Area in the morning, you will first need to be body marked as well as have your bike number attached to your bike. After the event, to retrieve your bike, you will need to show your bib number to the volunteer & to match it to the number on your bike to exit the Transition Area.
