After completing the Edinburgh Half Marathon in May 2023, Esther and Jo are back… but with bigger dreams. This year, against all odds, we’ve signed up for the 2025 Mont Blanc Marathon. Why are we telling you this?

Firstly, because we’ll need all the mental strength and encouragement we can get! The Mont Blanc Marathon is no ordinary race—42 km, 2,500 meters of elevation gain, and an iconic trail starting in Chamonix, winding through the breathtaking yet unforgiving alpine landscapes of Haute-Savoie. Truth be told, we may not fully grasp what we’ve signed up for—but we know exactly why we’re doing it.

Beyond the personal challenge, we are running to raise €650 for four incredible organizations that are making a real impact in the fight against disease, in advancing medical research, and in supporting local sports:

Vaincre les Maladies Lysosomales – This organization focuses on advancing research and improving access to care for rare lysosomal storage diseases. They provide crucial scientific information, support for families, and promote better treatments for those affected.

Trail Runners Against Muco – This organization is dedicated to fighting cystic fibrosis (CF). They raise funds for vital research to develop more effective treatments and, ultimately, a cure for this life-threatening disease.

Ultra Sports Science – Focused on researching ultra-endurance sports, this group works to understand the physiological impacts of extreme sports on the body, aiming to improve safety and health for athletes in the ultra-endurance community.

Club de Sport de Chamonix – A local organization dedicated to promoting sports and healthy activities within the Chamonix community, supporting young athletes and making sports accessible to all, no matter their background or level.

We hope you will consider sponsoring us in taking on this challenge for a worthy cause! Thank you for your generosity and encouragement—we’ll need both to reach the finish line!

With gratitude,

Jo & Esther
