Spectator Info
SWIM
6:30a – 7:30a Swim Start
Howard Amon Park
The parks along the Columbia River provide a beautiful setting to watch the swim. Sunrises here are magical and the energy of the race is invigorating.
Watching the start of the race is exciting, but it requires detailed planning. To view the Start at Howard Amon, spectators can find street parking near George Washington Parkway (or ride Ben Franklin Transit) then walk to the start area at Howard Amon. Once you’ve arrived, make your way to the main dock area where athletes start the swim. You can line the riverbank to watch the athletes enter the water and if desired you can walk toward Columbia Point Marina to watch them exit.
6:50a – 8:40a Swim Finish
Columbia Point Marina
There is only one entrance into Columbia Point Marina, and the bike and run courses limit access in and out. Because of this, the only way to access Columbia Point Marina is by walking or shuttling in from remote parking areas. Access by personal vehicles is prohibited on race day. Shuttles will run a loop from the City of Richland Building parking lot (651 Mansfield St.) and the Richland Federal Building parking lot (825 Jadwin Ave.) to Columbia Point Marina, beginning at 4:00 a.m. but athletes will have priority boarding from 4:00-7:00 a.m. It is estimated that shuttle spots for spectators will be available beginning around 6:00 a.m. To catch the shuttle, spectators can park in available lots as indicated. Please watch for extra pedestrians and traffic in the area and observe all street and traffic laws and signage.
Shuttles will continue to run in a loop from shortly after the start of the race until the last athletes exit the water and start their bike.
Once you’ve arrived at the Marina, make your way to the main boat ramp area where athletes finish the swim. As they exit the water, athletes run up the beach near the ramp to where their bikes are mounted in a fenced transition area in the parking lot (T1), then walk their bike to the starting chute before mounting for the bike course.
Spectators can line the transition area and the beginning section of the bike course to watch the cyclists head out on Columbia Point Drive toward Bradley Boulevard.
BIKE
6:50a - 8:50a Bike Start
9:00a – 1:00p Bike Finish
Columbia Point Marina
As noted in the Swim section, watching the action at the bike transition area and finish line requires detailed planning. There is only one entrance into Columbia Point Marina, and the bike and run courses limit access in and out. Because of this, the only way to access Columbia Point Marina is by walking or shuttling in from remote parking areas. Access by personal vehicles is prohibited on race day.
Shuttles will run a loop from the City of Richland Building parking lot (651 Mansfield St.) and the Richland Federal Building parking lot (825 Jadwin Ave.) to Columbia Point Marina, beginning at 4:00 a.m. but athletes will have priority boarding from 4:00-7:00 a.m. It is estimated that spots for spectators will be available beginning around 6:00 a.m. To catch the shuttle, spectators can park in available lots as indicated. Please watch for extra pedestrians and traffic in the area and observe all street and traffic laws and signage.
Shuttles will continue to run in a loop from shortly after the start of the race until the last athletes exit the water and start their bike. Limited shuttles will be available between 7:00 a.m. to 6:00 p.m.
The bike transition area is in the parking lot at Columbia Point Marina. After exiting the water, athletes will pick up their bike in the transition area and head out on the bike course. After completing the bike course, athletes rack their bike in the transition area then head out onto the run.
Spectators can line the transition area and the start/finish sections of the bike course on Columbia Point Drive.
RUN
9:30a – 4:30p
Make your way to any of the Parks along the River Front Trail from Columbia Point to WSU Tri-Cities for a beautiful setting for watching the Run. Spectators can line the River Front Trail and cheer the athletes on as they complete the last segment of the race. To see the culmination of it all, gather around the Finish Line at Columbia Point Marina.
Athlete Spotlight
Ashley Singleterry
What initially drew you to the world of triathlons, particularly the IRONMAN 70.3 distance?
I always admired endurance athletes. Marathons, Triathlons, ultra-marathons and I always thought “it’d be so cool to do a triathlon before I’m 30…. But I don’t know how to swim”.
How do you approach the multi-discipline nature of IRONMAN 70.3 races in terms of training and preparation?
I focused on my weakest area (swimming) and did maintenance training with the other two. Now in this point of training I am incorporating them all together and building my cardiovascular health and endurance. I never forget strength either!
What challenges have you faced along your athletic journey, and how have you overcome them?
I didn’t know how to swim. I never learned as a child. I signed up and reality set… “I need to learn how to swim”. I started off alone with YouTube videos just flopping around, eventually got lessons and now I’m set to finish 1.2 miles in under an hour.
Can you share a memorable moment or achievement from your athletic career?
I never thought I’d be athletic. I thought my diabetes would define who I was. My first run was the virtual Bloomsday in 2020, I had never run anything more than 4 miles. Once I completed the 12k I thought to myself “I can do this” and have been chasing more miles since. I completed my first 1/2 marathon in October!
How do you balance your athletic pursuits with other aspects of your life, such as work, school, or family?
Working full time is tough, fighting the mental battle of being tired or burnt out from the day and having to go train is the biggest hurdle. Being sore and working with animals is the WORST! But I know my body is capable, if I tell it to keep moving it will. I also bring my husband along for the ride, he is the motivator, the pacer, and the comedic relief I need when I’m ready to drop.
What message or advice do you have for aspiring athletes in our community? DO THE THING!
Sign up for the race! Chase the impossible!! You’d be surprised at what you are capable of. Set the goal and GO FOR IT!
Logan Webbenhurst
What initially drew you to the world of triathlons, particularly the IRONMAN 70.3 distance?
Several years ago, I saw a friend of mine complete his first Ironman and it inspired me to sign up for a half marathon. Fast forward 3 years and about 15 half marathons later, I decided to sign up for my first 70.3 to show my daughter that anything is possible if you work hard enough for it.
How do you approach the multi-discipline nature of IRONMAN 70.3 races in terms of training and preparation?
Knowing that I have a 9-month-old daughter at home, I know that I need to wake up early to get my first workout in before its time for her to wake up. Utilizing my time appropriately, I know that I can squeeze another one in before being able to spend time with my family in the evening. It's about knowing what your priorities are and making time for what matters.
What challenges have you faced along your athletic journey, and how have you overcome them?
The biggest challenge is people questioning whether I can accomplish the goals I have set for myself. This includes friends and family, but I use this as motivation to show that anything is possible
Can you share a memorable moment or achievement from your athletic career?
Running a half marathon PR for the first race my daughter ever saw me run and being able to hold her right after I finished
How do you balance your athletic pursuits with other aspects of your life, such as work, school, or family?
I schedule everything in my day, and I make time for what matters. That means making time for working out, spending time with my wife and daughter, doing my job, taking my dog for walks as well as managing a personal life.
What message or advice do you have for aspiring athletes in our community?
If it matters to you, you will make time for it
Heather Johnson
What initially drew you to the world of triathlons, particularly the IRONMAN 70.3 distance?
I initially started training for triathlons in 2017 because as an obese healthcare provider, I felt like a hypocrite telling my patients they needed to eat healthy and exercise. I wanted to be a good example. Then I decided I wanted to do a full Ironman for my 40th birthday in 2019 and I did another full distance in 2021. However, I have children, a husband, a job and an aging body and the training/racing a full distance puts significant stressors on all those things. The 70.3 distance gives me all the fun of training and looking forward to the race without the threat of injury or divorce, and I have time for other hobbies as well.
How do you approach the multi-discipline nature of IRONMAN 70.3 races in terms of training and preparation?
I cycle nearly every day because it is my favorite discipline, I run 2-3 days per week, and I swim as little as possible. Hahaha. Maybe 1-2 times a week for a month before a long course race like 70.3.
What challenges have you faced along your athletic journey, and how have you overcome them?
My worst challenges have been injury and illness, which tends to put a damper on training. I’ve had kidney stones, sprained an ankle, struggled with hip pain, crashed my bike a couple times and broken a rib and a clavicle. I’ve adjusted my training to doing a lot of indoor training where injury and crashing are far less likely, avoiding riding in the rain, avoiding the bike path, done physical therapy to rehab my hip and shoulder, etc.
Can you share a memorable moment or achievement from your athletic career?
I suppose my most memorable moment was becoming an Ironman at IMAZ in 2019.
How do you balance your athletic pursuits with other aspects of your life, such as work, school, or family?
I have come to accept that I will not win my age group or qualify for the world championships without training to the detriment of other things and people in my life. Sometimes I will skip a workout to hang out with my daughter or husband and that is ok.
What message or advice do you have for aspiring athletes in our community?
I started out being very overweight, not able to run a mile or ride 10 miles, and now I’m an old lady that has lost 80 lbs. and kept it off for the most part for 6 years, feels good about her health, and can do 140.6 or 70.3 miles in a few hours.
