Cassie’s 300 was created in support of Cassie and her family as they navigate her DIPG diagnosis, and to bring people together through movement, kindness, and community.
Alongside supporting Cassie directly, this fundraiser is also raising money for Braintrust, a charity that supports people affected by brain tumours and their families.
By taking part or donating, you are helping Cassie while also contributing to wider support, resources, and research for others facing similar journeys.

Cassie’s 300 was a community challenge where we aim to collectively complete 300 kilometres on the RowErg and SkiErg as quickly as possible.
The challenge started at 7am, with participants contributing metres throughout the day. Everyone’s distance adds up to a shared total, and together we worked towards reaching the full 300km.
You could take part for as long or as little as you like. Every metre counts.
