Boulderthon

Your resting heart rate isn’t a score you need to “win.”

A lower number isn’t automatically better, and a higher number doesn’t automatically mean something is wrong. Resting heart rate can vary based on fitness level, stress, sleep, hydration, medications, hormones, and more.

What does matter is giving your heart regular opportunities to work. Consistent exercise that safely raises your heart rate can strengthen your heart, improve cardiovascular fitness, and support your overall health.

It’s not about chasing the lowest resting heart rate. It’s about building a stronger, healthier heart over time. ❤️

We know summer training is brutal, but necessary.

To those of you in the thick of it, just remember the hard training right now makes for an easy fall race later (it’s us, we’re the fall race).

Boulderthon is giving back to the place we’re proud to run, train, and call home. 💚

Not every ache or pain needs emergency care, but some injuries shouldn’t be ignored.

Chelsea Holt, PT, DPT, of CU Sports Medicine & Performance Center shares how to tell when it’s time to see a physical therapist. Persistent pain, swelling, limited mobility, weakness, or an injury that’s keeping you from doing the activities you love are all signs it’s worth getting evaluated.

The sooner you understand what’s going on, the sooner you can start the right treatment and get back to moving with confidence. If something doesn’t feel right, don’t wait for it to become a bigger problem. 💪

But good news for you 😉

The finish line effect: exhaustion, relief, joy… and that moment when it all hits at once.

We can’t wait to see you there.

Heart health doesn’t take the summer off, but your workout might need a few adjustments. ☀️❤️

Dr. Robert Shapiro, interventional cardiologist at Boulder Heart, shares his top tips for staying active while protecting your heart during hot weather.

A few simple precautions can help you enjoy your favorite summer activities safely. Save this post for your next outdoor workout and share it with a friend who’s training in the heat. 💙

If you’re more of a mountain, trees, and fall leaves kind of runner, where enjoying the sights & scenery is 50% of your “why”, then Boulderthon is calling for you.

Months of training. One perfect day.
