Course maps

Swim, Bike, Run

Every athlete and every relay team covers the same three legs. The courses are well marked with arrows and tape.

Bike

9 km 5.6 mi

Exit east from transition onto the gravel path, watching for pedestrians, and ride around the lake past the boat launch, the playground and the dog park into fun singletrack. Climb into the Expert Loop, which drops you down some sweet switchbacks, until the trails wind back to the main gravel trail. Turn left and ride the gravel past the tennis courts back to transition. Enjoy the ride!

Run

4.1 km 2.6 mi

Exit east from transition onto the gravel path and stay on it, keeping the lake on your right all the way around. Always stay right as you run clockwise: if you have turned off the gravel trail, you have gone the wrong way.

FAQ

Questions, answered

Do I need a wetsuit?

A wetsuit is not required.

Can I ride my gravel bike?

Yes, but this is a very challenging bike course and we recommend a mountain bike. Whatever you ride, we highly recommend pre-riding the course in training.

What is the water temperature on race day?

Lake Padden will likely be in the 68 to 74°F range on race day.

How does the relay work?

Relay teams exchange the timing chip inside the transition area.

What if I only want to do one of the sports, like running?

That works. Find teammates to form a relay: they can do the swim and bike legs while you run.

What is your refund policy?

Until July 1 we can refund your entry minus 15% (to cover credit card processing and administrative fees), or transfer your registration to the following year. No refunds or transfers after July 1.

I’m not a USAT member. Can I still race?

Yes. USAT offers a one-day license, and it is included in your race entry, so you are covered.

Can a friend pick up my packet?

No. USAT rules do not allow it: you must show your ID and pick up your own packet.

Is drafting allowed?

Yes. USAT section 5.10 Position Fouls (Drafting) “shall not apply to off-road triathlons and duathlons and shall be excluded from enforcement at those events.”

What time should I arrive?

Check-in and transition open two hours before the race starts. Plan according to your needs.
