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 is a community challenge where we aim to collectively complete 300 kilometres on the RowErg and SkiErg as quickly as possible.
The challenge starts at 7am, with participants contributing metres throughout the day. Everyone’s distance adds up to a shared total, and together we work towards reaching the full 300km.
You can take part for as long or as little as you like. Every metre counts.
When you arrive, you'll be greeted and shown over to a machine.
You're welcome to:
Once you've completed your metres, you'll record them on the total board so we can track our collective progress.
You can:
Please make sure you complete a warm up before and cool down after your effort. This is about movement, not pushing your body beyond any limits.
Thank you so much for being here and for supporting Cassie’s 300. Whether you’re taking part on the day, donating, or simply sharing the page, it really does mean the world.
Below is everything you need to know for the day. Please have a quick read so you know what to expect.

You may be sent a rough time slot, this is just to help spread everyone out. If you need to swap, drop back in later or stay longer. That’s absolutely fine, it is all flexible.
If you’re not sent a specific time, please arrive within your allotted 4-hour block to allow enough time to take part.
We will have a running total board. Once you’ve finished your distance, you can update the board. You’ll be able to see our collective total building across the day.
There will be light refreshments (some cakes, drinks etc.) but feel free to bring your own food, especially if you’re planning on staying for a while.
There is one toilet on-site, so please be mindful.
Please car share where you can to save on space. The road down to the studio is a little bumpy with potholes, drive carefully,
There will be QR codes for donations and the cake stall, so cashless payment is preferred (but we will find a way if that’s tricky?)
There may be some photos and videos taken during the day. We’ll always warn you first, and you can absolutely opt out, just let us know.
The raffle will be drawn at the end of Sunday. You can purchase tickets digitally online or via a QR code. Please make sure you are able to collect the prizes that are not digital.
This day is about kindness, community and movement. You can leave whenever you need to, come back later if you would like or just hang around and support. We’ll keep the energy going as long as we need to.
Any questions, just let me know.
Your target time is listed in the email.
SEE YOU THERE
