We’re sending a huge congratulations to Mhairi Duncan for completing the Lisbon Marathon on 25th October 2025, raising funds and awareness for XLH UK in the process.

Mhairi took on this challenge not only as a personal milestone but to support the community. And she’s done a remarkable job. Despite some travel mishaps along the way, she made it to Lisbon and ran the full marathon!

Reflecting on the big day, Mhairi said:

“What an experience! So incredibly grateful to be able to run an entire marathon, and raise such a great amount for an amazing cause!”

Before her marathon, we interviewed Mhairi to talk about her XLH journey, her passion for fitness and how she adapted her marathon training as a personal trainer living with XLH. You can watch the full interview here.

We’re so proud of Mhairi for her incredible achievement and her dedication to raising awareness and hope for the XLH community. If you’d like to support the fundraising, please visit her page here.

Thank you, Mhairi – and congratulations again!
