Boulderthon

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.
⠀⠀⠀⠀⠀⠀⠀⠀⠀
Hydrate before you head out, exercise during the cooler parts of the day, listen to your body, and don’t ignore symptoms like dizziness, chest pain, or unusual shortness of breath.

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.

Mountains aren’t the only thing we’re moving. ❤️

This Boulderthon, .mountains.together and Brandon are taking on a challenge that’s bigger than the miles ahead. Brandon is a 40-year-old athlete living with cerebral palsy, and together they’re running with purpose through the “Brandon Moves Mountains” campaign—to raise funds for Children’s Hospital Colorado and support the incredible kids and families they serve.

Every step, every mile, and every donation helps make a difference.

If Brandon’s story inspires you, they’d be honored to have your support. The donation link is in our bio and stories.

Together, we can move mountains. 💙⛰️🏃‍♂️

🎨 Excited to host our second volunteer opportunity, where we painted the handball wall, a shed, and de-weeded at ’s Tom Watson Park. We’re so grateful to the community for the opportunity and to our volunteers for making it happen. See you next time! 👋
