How to register

We would love for you to join us at this iconic event, taking steps to help everyone affected by ovarian cancer.

There are two ways that you can join Team Target: 

Charity Place

We have a limited number of guaranteed places in this event.

For this option, we have a £15 non-refundable registration fee and ask that you pledge to raise the £300 minimum fundraising target - with this we could fund more than a day of life-saving research.

Own Place

If you were one of the lucky ones and secured your own place via the Cardiff Half Marathon ballot, or via a membership, we would still love for you to join Team Target!

For this option, we have no registration fee or minimum fundraising target, but we hope you'll raise as much as you can to stop ovarian cancer devastating lives. 

We will ask for proof you have secured your own place independently from the charity - so have your confirmation email ready.

What you can expect from us

Support from a member of the fundraising team, to help you every step of the way.

A fundraising guide filled with help, advice and top tips to increase your sponsorship.

Free fundraising materials to help you raise awareness of your challenge and the charity.

A Target Ovarian Cancer running top.

Access to useful training and nutritional tips. 

We'll offer you the same high level of support whether you join us with a charity place or with your own place.
