Racing Against Time: On Ironman, Ultramarathons, and the Quest for Transformation in Mid-Life

Racing Against Time is the inspiring true story of Jeff Weiss's incredible transformation in midlife. At 48 years old, out of shape and searching for new purpose, Weiss took on his first 10K-an event that would spark a profound personal evolution. What began as a simple challenge soon turned into an extraordinary journey of endurance, perseverance, and self-discovery. Within a decade, he pushed beyond perceived limits, becoming an Ironman and ultramarathoner, proving that age is no barrier to strength and ambition.

Kirkus calls Racing Against Time: “An engaging and reflective life journey that captures the grit, grace, and quiet triumphs of endurance sports.” It compares Racing Against Time to one of the great running books of recent years: “The memoir’s honest reflections on physical challenges and mental resilience resonate alongside classics like Haruki Murakami’s What I Talk About When I Talk About Running, blending the physical demands of sport with introspective growth.”

“If you’re looking for inspiration and motivation, Racing Against Time will get you going!”

New York Times Bestselling Author and legendary ultramarathoner Dean Karnazes

“Part memoir and all inspiration, Racing Against Time has it all: family, life, midlife transformation, tragedy with triumph, and, thankfully, a whole lot of UltraRunning. I’m stoked about another book from Jeff, and I think you will be too.”

Travis Macy, author of The Ultra Mindset: An Endurance Champion’s 8 Core Principles for Success in Business, Sports, and Life.

“Weiss’s story illustrates the power and joy of mid-life transformation.”

Chip Conley, bestselling author of Learning to Love Midlife and Founder, Modern Elder Academy
