Calling all strength stars: your DriTri dress rehearsal is today. 🎬 Supersets in Act 1, full performance in Act 2. Spoiler: there will be sweat. 💦 Who's ready for the real deal after that?

Meet Natasha from OTF Estero 🧡

For Natasha, More Life isn’t just about milestones — it’s about moments. The ones where she’s running side by side with her son. Laughing. Moving. Living fully.

She never imagined she’d run 50+ miles during Marathon Month or complete the DriTri — but she did. She pushed beyond what she thought was possible.

“By challenging my body in ways I didn’t think I could,” she says, “I’ll be able to keep running and playing with my son for a lifetime.”

Because every rep, every step, is building a lifetime of moments that matter most.

09/01/2025

You’ve been building up to this. Every rep, every meter, every minute. DriTri isn’t just a challenge, it’s a celebration of how far you’ve come. Whether you go Full, Sprint, Strength, or Team … just know: You’re not starting from scratch. You’re starting from strength. And you’ve got tri-hard written all over you 🧡

📆 Sept 19-21. Let’s go. Register now on the mobile app or at the front desk.

That post-finish line glow? You wear it well 🌟 A month of sweat, smiles, and serious mileage — now drop your distance and let the celebration begin ⬇️🏅

08/29/2025

September is here which means so is DriTri! 🍂🍁🍃Signups start on September 1st, so get ready to row, rep, and run/power walk your way through the challenge!

It’s not fall until your legs are sore and your coffee’s seasonal. Press, squat & lunge for joy — we brewed this one just for you ☕️🏋️‍♀️

08/26/2025

Since joining Orangetheory Lawrence in September 2024, Andres has been on a mission to live a more active, balanced life — and he’s doing just that.

Originally from Costa Rica and now studying supply chain management and accounting at KU, he’s juggling workouts, recovery, and academics with heart and hustle. His favorite part of OTF? The community. Because nothing beats the kind of motivation that comes from pushing through a tough block side by side with friends.

Since starting, Andres has gained strength and built muscle, and he's now working toward bouncing back from a knee injury — one step at a time. All with Timber on blast and the Jayhawks in his corner. 🏀

We’re cheering you on every rep of the way, Andres!

08/26/2025
