At 48, he ran his first 10K. At 61, he finished a 72-mile ultramarathon.

In this powerful episode, Jeff Weiss joins Mark and Kelli to share how movement, mindset, and starting late transformed his healthspan. From his first 10K in his late 40s to Ironmans and ultras in his 50s and 60s, Jeff proves it's never too late to reinvent yourself.

We talk about: • How loss pushed him into fitness • Chunking hard goals into doable pieces • Training for marathons, Ironmans, and ultras • Why "healthspan" matters more than lifespan • How to stay strong, mobile, and energized after 50

If you need proof that your best years are still ahead of you — this episode is it.
