Your Coach & Guide
I started running marathons at age 50 — not to win, but because my friend Mark was fighting prostate cancer and needed teammates. That first NYC Marathon with Fred's Team changed everything for me.
Since that 2019 race I've run 10+ marathons, become a USATF and RRCA certified coach, and helped Team Mark raise over half a million dollars for cancer research at Memorial Sloan Kettering Cancer Center.
I know what it feels like to start from scratch in midlife. I know the overwhelm of signing up for your first marathon and having to raise thousands of dollars for charity at the same time. I wrote the book — literally — to help people just like you.
Whether you're 25 or 75, a couch potato or a former athlete returning to the sport, your journey can start today. Your purpose will carry you through.
"Fast or slow, finishing makes you part of a rare group — less than 1% of people will ever complete a marathon. That accomplishment is extraordinary." — Tom Walsh, Running for Your Why

The Story Behind Run4Why
Run4Why was born from one of the most inspiring acts of human spirit: watching a friend fight cancer and choose to run the NYC Marathon anyway.
Mark Kourey ran the NYC Marathon in 2018 while in treatment for prostate cancer at Memorial Sloan Kettering Cancer Center. His smile crossing that finish line — despite the pain — changed everything for Coach Tom and six other friends who decided to join him the following year.
That group became Team Mark, a team within Fred's Team — the official charity running program of MSK. Since our inception in 2018, Team Mark has raised over half a million dollars for cancer research.
"It makes a difference to this one." That's why we run.
Want to run for a cause you love?
Coach Tom can guide you through the entire process — from choosing a charity to crossing the finish line.
Start Your JourneyThe PSA test for prostate cancer is optional but can save lives. Every man over 50 — or with a family history — should ask their doctor to check their PSA annually. Early detection is the best defense. Tell the men in your life.

"Running for Your Why" by Tom Walsh covers everything an everyday athlete needs to know: training and nutrition for runners over 40, hydration, sleep, weight training, stretching, and the art and science of fundraising through endurance sports. It's part memoir, part practical guide — inspired by Tom's personal journey and the story of his friend Mark Kourey.
Fred's Team is the official charity running program of Memorial Sloan Kettering Cancer Center, founded in honor of NYC Marathon founder Fred Lebow. Since 1995, Fred's Team has raised over $100 million for cancer research. Team Mark is Coach Tom's team within Fred's Team, founded in 2018 for his friend Mark Kourey who ran the NYC Marathon while in cancer treatment. Team Mark has raised over $500,000 for MSK.
