Running With Purpose
How a man found a reason to run to support a selfless ADRA initiative in Japan.
December 8, 2025 | Silver Spring, Maryland, United States | ADRA International and Adventist Review
Around the world thousands of runners lace up their shoes not only to test their limits but also to support causes that create meaningful change. Known as charity runs, these marathons or half marathons encourage participants to run or walk to raise money and awareness for a specific cause or organization. The Tokyo Marathon Charity Program is one of the ways athletes transform personal goals into global impact. Meet Dietmar Grellmann, a charity runner from Sacramento, California, United States, whose passion for running is matched by his commitment to helping others.

When asked what it means to participate in the Tokyo Marathon as a charity runner, Dietmar explained: “One of the wonderful things about running is that runners don’t just run for themselves; they can also run for their community or for others. Many marathon races have a purpose; they honor someone or something, whether it’s protecting the environment or helping people in need. Being a charity runner is truly an honor for me.”
For him, every mile is an opportunity to make a difference.
A Family Connection to ADRA
Dietmar’s relationship with the Adventist Development and Relief Agency (ADRA) began long before he ever put on a race bib. When his children were young, the family made a tradition of choosing gifts from the ADRA gift catalog each Christmas. The catalog helped his children understand how their choices, such as providing school supplies, livestock, or clean water, directly supported people in need.
That experience shaped his family’s values. Years later his daughter spent a year volunteering at a children’s home in Zimbabwe, deepening their commitment to development and humanitarian work.
“ADRA has a wonderful mission,” Dietmar said. “When crises arise, they are there on the front lines, bringing help to those who need it most. I think that’s truly wonderful.”

How Running Became Part of His Life
Dietmar didn’t grow up as a runner. His journey began in 2010, at age 41, through a company-wide 10,000-step challenge.
“I started getting up early to walk, and I really began enjoying that routine. And that led me to running,” he recalls.
The turning point came during a Thanksgiving visit to his brother’s family in Boston. His brother invited him to join a local Turkey Trot 5K, and the joy of running that 5-kilometer race sparked what would become a global running adventure.
Running Around the World—With His Brother
Since then, Dietmar has completed the Boston, New York, Berlin, and Chicago marathons. Running the Tokyo Marathon 2026 Charity will bring him one step closer, leaving only London and Sydney before he finishes all seven World Marathon Majors.
“I’ll be running Tokyo with my brother. He’s also a charity runner for ADRA Japan,” he said. “We’ve already run New York, Berlin, and Chicago together.”
Running has become a meaningful way for the brothers to stay connected, even though they live far apart.
What Keeps Him Motivated
“One of the things I love about running is that you’re not competing against anyone else; you’re competing only with yourself,” Dietmar shared. “You set your own goals and find joy in achieving them.”

He reflected on why running has remained such an important part of his life: “I was never very good at team sports when I was young, but through running I discovered something I was good at. It feels good to be good at something. I enjoy the entire process—training, nutrition, stretching, injury management, all of it. Marathon running is the only sport in which everyone who puts in the effort can cross the finish line and receive a medal. That feeling of accomplishment when you give it your all and finish strong—that’s what brings me the greatest satisfaction.”
Looking Ahead to the Tokyo Marathon 2026 Charity
Dietmar is focused and excited about the challenge ahead. “I always want to run a good time. I push myself and strive to do my best, but I also want to cross the finish line feeling strong and happy. Finding that balance between performance and enjoyment is important to me. The Tokyo Marathon 2026 Charity is a very special race, so I really want to perform well and enjoy every moment of it.”
His dedication reflects the spirit that drives ADRA’s mission: compassion, service, and a commitment to uplifting others. Runners like Dietmar help expand ADRA’s impact, turning every mile into hope for communities around the world.
