Set up a JustGiving page

Setting up a JustGiving page is a great way to fundraise online. Share your link with family, friends and colleagues, and watch the donations roll in.  

You can use JustGiving to explain why you’re taking on your challenge for Target Ovarian Cancer, keep track of how much you’ve raised, and even share your training progress. The more you update and share your JustGiving page, the more donations you’ll receive.

Set up a JustGiving page for your 'Inflatable 5k' event today!
