Siri is the most resilient, loving, inspiring, authentic, and brilliant woman I have ever met. She lives each day to the fullest and is filled with gratitude for all life and for every breath she takes. Her joy, light, and exuberance illuminate all around her. She is a two-time World Champion Triathlete, a top 10 global speaker, a best-selling author, a Tony Robbins keynote speaker at his worldwide events, saves horses from abuse, and so much more. Her life's mission is to help others. Here's a very condensed version of her story.

In her early 20s, Siri decided she wanted to become the world's #1 triathlete even though she didn't know how to swim and finished dead last in the competitions she entered. After staying focused and resilient through the MANY ups and downs, eight years later, she was crowned the Triathlon World Champion! She retired as the world's #1 triathlete. In 2023, she was inducted into the World Triathlon Hall of Fame. She has also been inducted into four other triathlons and the school Hall of Fames. She then coached multiple Ironman world champions and Olympic medal winners. She is currently listed as one of the top 12 triathlon coaches in the world by Triathlete Magazine. She has always faced each day with love for all things and determination to help others with her heart full of love and gratitude.

But her biggest challenge was yet to come. In 2019, when she went in for routine bloodwork for a hip replacement surgery, they found she had acute myeloid leukemia (AML) with a genetic mutation that gave her a 10% chance to live. She and her wife, fellow champion athlete Rebekah Keat, were completely shocked and devastated. But as the news sunk in, she made a decision right then and there that she was not a statistic, and she was going to live!

She was treated by renowned doctors Dr. Gutman and Dr. Pollyea at UC Health in Colorado. She was incredibly grateful to be accepted into their clinical trials to treat AML. There were times during treatment when she was so sick she couldn't move, and many of her friends came to say their final goodbyes. But she KNEW she would survive and thrive. She focused on what she wanted to do when she was cured ― run to the top of her favorite trail with her beloved wife. This is what she did! She has repeated this over and over the past four years of being cancer-free!

Siri has written a best-selling book about her journey, Finding A Way: Taking the Impossible and Making It Possible. It's a wonderful book about her life and how she conquered AML. She also includes inspiring ways for readers to do the same in their own lives. That is her life's mission, to help others. It's the best book you will ever read.

She recently went to Washington D.C. and met many people from Blood Cancer United, formerly The Leukemia & Lymphoma Society (LLS) as they lobbied for a bill that would allow more access to the general public for clinical trials. She believes this is so important. While in D.C., UC Health Colorado previewed a clip from a documentary they produced about her life. It's called Tri Me: The Siri Lindley Story. In it, they follow her through her AML treatment and incredible recovery against the odds. It's the most inspiring documentary you will ever see. She is the most inspiring, strong, and loving person you will ever meet.
