FAQ
Please find our frequently asked questions below:
How do I sign up and collect donations?
You can register for the challenge and your free WWF swim badge by choosing your distance and following the links: 5k, 10k, or 20k - whichever suits you best!
Share your fundraising page with friends and family and ask them to sponsor you to swim your kilometres over August.
I'm worried I won't get any donations
Remember, you’ve got plenty of time to collect donations, so try not to worry. Here’re some of our top fundraising tips:
Donate to your own fundraiser – it shows your friends and family that you’re taking your challenge seriously!
See if your employer has a ‘matched donations’ policy – you could potentially double the amount your raise!
Keep your friends and family updated with your challenge and they'll donate once they see what you're doing.
Personalise your fundraiser blurb & photo - this makes a huge difference! Tell people what's motivated you to take on the challenge.
How do we track our kilometres and do I need to provide evidence of completing them?
There's no need to prove you've completed your kilometres - but you're able to log your kilometres on your WWF fundraiser so you can keep track and share your progress with friends & family so they can see how well you're doing! You'll also receive a paper tracker with your WWF swim badge if you prefer to keep tally that way.
