Every marathon runner has a reason.

Shaun O’Sullivan’s reason is powerful. 🏃‍♂️💙

This April, Shaun O’Sullivan is taking on the 2026 London Marathon to support One YMCA.

Here’s the why behind every mile Shaun will run:

🌙 218,228 nights of safe, secure sleep given to people experiencing homelessness, offering safety when it’s needed most.

🏠 719 residents moved into settled accommodation, rebuilding stability and hope for the future.

🆘 1,360 survivors of domestic and sexual abuse received life changing therapeutic support.

👧 71,158 families engaged with support that helps children grow, learn and thrive.

💷 And through this work, One YMCA generated £16.3m in cost savings to the public purse, multiplying the impact of every donation.

Shaun is running to make sure this work continues — and grows.

Your support can help Shaun change more lives across Hertfordshire, Bedfordshire, Buckinghamshire and beyond.

Let’s get behind him and power every mile. 🙌
