Open to all ages; this is a great activity for the whole family! Each participant will receive a goody bag with commemorative swag. We are offering two levels of participation - Giving it a ‘Tri’ and Born to ‘Tri’.

The Challenge

Swim, Bike, Run!  The goal is to complete each leg of the triathlon between May 1 & 31, 2021.

Born to Tri: 1,750 yards or 700 minutes
Fun Fact: 1,750 yards is 70 lengths in a 25-yard pool. 

Swimming, water walking, water aerobics or any combination in the water counts towards your swim yards or minutes. PH Aquatic Park is open for lap swim and water fitness; check out the pool schedule for programs and hours.

Biking, scootering, skateboarding and anything with wheels counts towards your bike distance.

Strolling, walking or running all count towards your run miles! Check out our parks and trails for some running inspiration.

We will be using Challenge Runner to track your progress through the triathlon.  A link will be sent approximately 1 week before the event begins, to set up your Challenge Runner account. With Challenge Runner you will be able to keep track of your progress, see the progress of everyone else in the triathlon, and earn badges for completing different milestones.

We are operating under the honor system. Challenge Runner is compatible with many fitness devices, including Fit Bit, to track your progress. You can also manually enter your activity into Challenge Runner.

Goody Bag pick-up will be Saturday, May 1, 10:00 am-11:00 am at the Walnut Sports Basement store (1881 Ygnacio Valley Road) and will include a discount/coupon code. Bags not picked up on May 1 will be available for pick-up at PH Aquatic Park Monday, May 3-Thursday, May 6, 3:30-7pm. Thanks to Sports Basement and GoGo squeeZ for their support of our goody bags!
