Triathlon Course Information
Swim Course – Counter-clockwise swim at Sunset Beach in Lake Sammamish (1 full triangular lap for sprint, 1 smaller triangular lap for super sprint) at the eastern beach area in Lake Sammamish State Park called Sunset Beach (near the playground). The cove is protected from wind and boats. There will be lifeguards onsite if a rest is needed or to help you safely finish the swim
Bike Course –
SAFETY FIRST – Remember, this is NOT a closed course. There will be everyday beachgoer vehicular traffic traveling in and out of the park. They are probably not aware of the triathlon taking place and may not see you on your bike. Please keep your wits about you while exiting and returning to the park. Our course monitors will do their best to allow you to move around vehicles but your safety is ultimately on you. Saving a few extra seconds on your bike is not worth putting yourself in unnecessary risk. Please be safe.
Sprint Distance, Super Sprint, Relay Teams and Duathlon participants will ride north through Issaquah and north along East Lake Sammamish Parkway through both Issaquah and Sammamish before turning around near NE Inglewood Hill Rd. Participants will ride the same course back from the northern turnaround before returning to the transition zone at Sunset Beach.
Through Issaquah, participants will have a full lane of traffic in each direction to ride in during their race. Through Sammamish, participants will ride in the bike lane/fog line on each side of the roadway in the same direction as traffic. Those lanes are over 8 feet wide and have enough room to pass. Please remember though, keep your wits about you when passing and stay within your cone lanes to stay safe.
Run Course – All participants will complete one loop throughout Lake Sammamish State Park’s different trails and pathways. The race course will be thoroughly marked for all participants and will be open until the last finisher returns. The trails are a mix of gravel (10%), packed grass/dirt (40%) and concrete (50%). There will be one water station on course and will be at the beginning of your run as you leave the transition zone. If you plan to need water along the course, please carry it. The run course is the same for all Sprint, Super Sprint and Duathlon participants.
Reminder – Lake Sammamish State Park will be open to the public and there will be everyday park visitors at the park along with triathletes. Parking is not free in state parks. Parking will be available within Lake Sammamish State Park at Sunset Beach, the site of the Seafair Triathlon. All participants will either need a Discover Pass annual State Parks parking pass OR will need to pay a daily fee of $10 to park. There will be multiple payment kiosks throughout Lake Sammamish State Park for participants to pay. We strongly suggest purchasing your Discover Pass or daily pass online BEFORE arriving at the park, we will not delay the triathlon start because of lines at the parking kiosk. To purchase online CLICK HERE.
If you’d rather not pay, you can either park within the neighborhoods and ride in or be dropped off.
Please remember – There will be many participants leaving or returning through the park on their bikes, please pay attention and allow bikers to continue their triathlon unimpeded if you’re mixed with cyclists while in your car.
