Seb's fundraiser for Billy's Battalion

Seb Williams is raising money for Billy's Battalion

The Lap - Lake Windermere Ultra Marathon · 12 September 2026

We are a newly registered charity (no. 1213415) dedicated to raising awareness of DIPG, a devastating childhood brain cancer, and funding better trials, better treatments, and ultimately, a cure. Billy the Brave was just 15 days away from his fifth birthday when he died on Easter Sunday, 31st March 2024 — only five months after his diagnosis. Billy’s Battalion is his legacy. Together, we can bring hope, drive research forward, and fight for every child’s future.

Story

In September I’ll be running The Lap Ultra Marathon to raise money for Billy’s Battalion.

Billy played at the same sports club as my son and, a few years ago, sadly lost his battle with DIPG - a devastating paediatric brain cancer that primarily affects children.

DIPG currently has no cure. Across the US and UK, nearly 400 children are diagnosed with this disease each year.

Billy’s Battalion was set up to raise awareness of DIPG and to fund better trials, better treatments, and ultimately help find a cure.

To support the incredible work Billy’s Battalion is doing, I’ll be taking on the challenge of running The Lap Ultra Marathon.

Any support, however small, would mean a great deal and is hugely appreciated.
