The Phoenix Energy Belfast City Marathon is the biggest marathon event in Northern Ireland. The event will take place on Sunday 3rd May 2026 and will start on the Stormont Estate.

This event is now SOLD OUT, but you can still get a charity place! Autism NI has limited places available on the marathon. Sign up today to secure your charity place.

It is £160 to register for a full marathon place, and we also ask runners to raise £500 minimum sponsorship to support Autism NI's regional services.

Why choose to run for Autism NI?

By running on behalf of Autism NI, you will be raising vital funds to support our local autism services across Northern Ireland. Sign up with us to receive an Autism NI t-shirt/running vest, support from our dedicated fundraising team and sponsorship pack.
