REMEMBERING ISABELLA DE LA HOUSSAYE

  
This year we are honored to present the second annual Isabella de la Houssaye Award to the top female finisher of the 5K race. Isabella was a dedicated endurance athlete and an advocate for early lung cancer screening. After being diagnosed with Stage 4 non-small-cell lung cancer, she continued her incredible adventures, running marathons, competing in Ironman triathlons, and inspiring countless others. A long-time supporter of The Watershed, Isabella played a pivotal role in organizing the Solstice Trail Run and always participated, bringing her family and friends.
