Is this event for experienced runners only?
The Cardiff Half Marathon has a welcoming atmosphere for both experienced runners and those who are new to it. We can provide you with training plans from the experts at Cardiff Half Marathon to help you reach the half-marathon distance. Many people who take part are new to running events, so you will not be alone.
What does my fundraising support?
Your funds will help us to make faster progress towards making ovarian cancer a survivable disease. Every day, 12 women die of ovarian cancer. Your support will mean we are able to fund research that focuses on the prevention and treatment of ovarian cancer, transforming how long and how well women will live. Your fundraising will also help us to raise awareness of the symptoms of ovarian cancer, so people know what to look out for, which saves lives.
Can you support me to fundraise?
Our friendly fundraising team is here to support you with your fundraising every step of the way. We can provide advice, materials, and ideas to help you smash your fundraising target. We allow our runners 4-6 weeks after the event to reach the minimum fundraising target, so there is plenty of time to collect sponsorship and raise as much as possible to support our vital work.
I think the Cardiff Half Marathon is too far away from me
The event is a fantastic excuse to go away and explore Wales for the weekend with tons to see, not least the vibrant city-centre neighbourhoods you’ll be running through. If you want to make a full weekend of it, Cardiff is a lively capital city offering unique attractions, world-class sports stadiums, vibrant entertainment, waterside eateries and seemingly endless parkland.
How do I pay in my money?
After all the hard work you’ve put into fundraising, it’s important that the money you raise supports the critical research that will transform futures for everyone affected by ovarian cancer.
