Ames Triathlon, Duathlon, Aquabike

Do you like to climb stairs? You will when you're done experiencing Ledges' famous hilly loops through scenic forest that features more steps than we care to count, two creek crossings, and one heck of a way to start your summer! $3 from every registration goes to the Friends of the Ledges who help maintain Ledges State Park to be one of the most amazing places in Iowa!

The Iowa Trail Run Series is not about spending a bunch of cash for no reason. You'll get a great race with clear marking and course support, with basic timing, a cool custom bib, and a rotating race item such as a BUFF, socks, a stocking cap, coffee mug, and aluminum water bottle. Signing up for the entire series includes a series backpack! Do you want a really soft and comfy tri-blend shirt with one of our Animal Icons? Great! Add one during your registration. We know some people have enough stuff in their closet and others may want to commemorate the day! Plenty of post-race food to refuel! Games! Giveaways from sponsors!

What is the Gladiator Assault Challenge?

Gladiator Assault Challenge is the Midwest's premier test of endurance, speed, agility, strength, and mental stamina. Gladiator Assault Challenge obstacle courses are a series of physically challenging obstacles (some natural and some man-made) that individuals or teams must navigate. These courses will challenge you with running, climbing, jumping, crawling, balancing, and MUD with the aim of testing overall endurance.

Your parents always told you not to play in the woods at night, right? Now's your chance to give it a go! Take on the challenge of a 5K or 10K at McFarland Park just outside of Ames. There's a great mix of single track trail, prairie, and gravel. You'll do it all as the sun sets on a beautiful Iowa summer night! $3 from every registration goes to the Conservation Partners of Story County who help keep Peterson Park, McFarland Park, and the other great public parks in Story County, beautiful!

B-INSPIRED 5K — Run. Walk. B-INSPIRED. Family/kid friendly event that includes CHEESE at the finish line!

THE LAST DAY TO GUARANTEE A T-SHIRT IS FRIDAY 9/26!!!!

T-shirts and race swag guaranteed to pre-registrants only. Day-of registrants will receive items as available

I’m so excited to bring the 1st Annual B-INSPIRED 5K to our community — a fun, feel-good event all about movement, mindset, and showing up for yourself. This race is for anyone and everyone. Come be part of it — and let’s B-INSPIRED together. Kids 8 and under are FREE and do not require registering/will not have bibs or timers. Kids/Families will start at the back to allow those who are chasing a PR a clear path to get started!

If you know me, you know I pour my heart into two things: Letter Eats by B — the small business I built from the ground up — and prioritizing my health, both mentally and physically.

I’ve been called inspiring or “goals” — but truthfully, I’m just committed. I show up — for my business, my health, and the people around me. And this 5K? It’s my way of creating space for YOU to do the same!

If you’ve ever been to my shop, you might have noticed my “b-inspired” wall in the bathroom. It’s filled with encouraging messages from customers, friends, and family — words I often find myself looking at when I need a boost. It reminds me that you have to find the things and the right people to inspire you to keep going.

Whether this is your first 5K, or you’re just coming to walk and be part of something positive — this race is for you. Set a goal, chase a PR, or simply take a break from the chaos of life and move your body. There’s no pressure — just a community coming together to move forward.

Let’s remind ourselves that strength isn’t always about speed — it’s about showing up, pushing forward, and being proud of exactly where you are. Never compare your journey to anyone else’s.

New to the 5K world? Not sure where to start? Don’t worry — the place I trust and train at every day, 6th Street Underground, is stepping in to help! I’m excited to share that Chad & Jenny are putting together a beginner-friendly training program designed to help you feel confident, strong, and ready to cross that finish line. Stay tuned!

Interested in volunteering? Please email lettereatsbyb@gmail.com

After the race there will be post race refreshments and as mentioned above CHEESE!

Purpose: The B-Inspired Scholarship will be awarded to a Boone High School senior who demonstrates drive, creativity, and passion for their future. Whether their dream is to start a business, or to pursue a career in sports, exercise science, kinesiology, athletic training, or another movement- or motivation-focused field, this award celebrates ambition and the courage to chase big goals.

This scholarship represents both sides of my journey:

Entrepreneurship – building my business, Letter Eats by B, from the ground up.

Athletics, Fitness & Self-Care – creating the B-Inspired 5K to encourage others to show up for themselves while reflecting my own love for fitness and self-care.
