Help us by giving yourself the ultimate challenge of running a marathon to fight cancer. There is no minimum sponsorship amount that you need to raise for an Irish marathon or mini marathon. We just ask you to raise as much sponsorship as you can.

Note: You must enter your chosen race as well as register with us. To secure your entry, please visit the appropriate marathon website. Registering with the Irish Cancer Society does not enter you in your chosen race!

To register additional people or a team, please CallSave 1850 60 60 60 where a member of our fundraising team can help you.

Looking for a marathon overseas? Visit our overseas marathon section.
