Episode Details

Larry Grogin is halfway through running 100 marathons in 100 consecutive days.

He started in New Jersey on March 24 and is making his way toward Southern California as part of Strides for Humanity, a run raising awareness and support for people living with Parkinson’s. Each day starts with the same challenge: cover 26.2 miles, manage what Parkinson’s brings, and get up the next morning to do it again.

Larry has spent decades around movement as a chiropractor, acupuncturist, and endurance athlete, having completed more than 300 marathons and 30 Ironman triathlons. Having been diagnosed in 2019 with Parkinson's, he marked his 71st birthday with the start of his run to show what movement can still look like after diagnosis.

He talks about the long warmups, the moments when his stride has to shorten, and the people along the road who help him keep going. At the center of the run is a simple hope: that someone sees what he is doing and decides to walk a mile, get out of bed, or do a little more than they thought they could.

Key Takeaways

➡️ Movement starts before the miles do.
Larry spends hours warming up before his body begins to feel available. The early work is patience, rhythm, and staying with it long enough to get moving.

➡️ Adaptation can be small and practical.
When his body resists, Larry shortens his stride, changes the pace, or gives himself time to rest. The goal is to keep moving in a way his body can handle.

➡️ One person moving can help someone else start.
Larry wants people with Parkinson’s to see the run and try something of their own. That might mean walking, running, getting out of bed, or doing a little more than yesterday.

➡️ Past challenges become tools.
Larry draws on decades of marathons, triathlons, and difficult races. Those experiences remind him that hard moments shift, and the next mile can feel different from the last.
