The bike segment takes place inside the park. As it gets dark, you will be required to use adequate lighting (white light) on the front of your bike and a red flashing light on the rear. The front white light should broadcast decently 10’ or more. We also highly suggest a headlamp attached to your helmet. Ensure you have sufficient batteries to last throughout the night. There is electricity available to charge spare batteries inside the race village.

The bike segment is a 5.0769 mile (8.169 kilometer) loop inside the park. You will start the bike demo the swim area.​

You’ll begin your bike down at the swim exit and ride your bike up to the race village location (red line on the diagram). At that point, you will begin your first loop on the bike course by heading out to the Park Loop Turnaround, riding back through the village to the Cabin Loop Turnaround and
final riding over the Finish Line (red line on diagram) at the race village location. This completes one loop of the course.

We have calibrated the course with the same measuring equipment used by the Olympic committee (it is called a Jones Counter) so we are accurate on the mileage. Remember, GPS data from your watch, with long distances and multiple loops, will often be incorrect over time. Our courses are carefully marked and measured. Do not rely on your satellite GPS watch as an accurate measurement.

Road bikes must be in good working order. Remember to inspect your bikes before the race so you do not have any mechanical surprises on the bike course. You may use more than one bike during the race.

You must wear an ANSI/Snell approved bike helmet during the bike course and have it buckled at all times when touching your bike. YOU MAY NOT DRAFT during this event. While on the bike segment, cyclists shall not work together to improve performance, efficiency, or position by teamwork or other joint conduct. All cyclists must assume and maintain a staggered riding position relative to the cyclists directly ahead. A variable time penalty shall be imposed for any violation of this. You may stop or walk your bike, but no time adjustments will be made.

The bike loop is pretty much flat with two medium size hills plus a few other small rollers. The turnaround point is just before the campground. There is a decent size opening in the road giving you a little extra room to make that 180 degree turn and head back to the village. Please be careful making your turn around and be aware of vehicles that may be entering or exiting the campground. We will have course signage out notifying motorists of the event. At the end of the day, cars are bigger than bikes so please stay alert and be aware of your surroundings.

No headphones are allowed. While you may carry a phone, you cannot use it as a communication device.

Single and half athletes must complete the bike segment within 13 hours of the race start (8:00 p.m. Friday), 1.5x athletes within 20 hours of race start (3:00am Saturday), Double athletes within 26 hours of race start (9:00 a.m. Saturday).
