What is Cupid's Undie Run?

It's the most fun you can have with your undies on!

Cupid’s Undie Run is an annual event that isn’t about running or winning…or even undies. It’s about putting the “fun” into fundraising for the Children’s Tumour Foundation (CTF) and helping adults, children, and families impacted by Neurofibromatosis (NF) find a pathway from fear to hope.

Cupid's Undie Run 2021 is a bit different. Different is good.

Are you ready to take on the Cupid's Undie Run 2021 Challenge?


Every 3 days a child is born with NF in Australia

NF is a genetic disorder that affects 1 in every 2,500 people and causes tumours to grow on nerves throughout the body, including the brain and spine. It is unpredictable, progressive and there is currently no cure

We run in our undies to shine a light on this devastating condition and to spread the message that stripped-down, we are all the same – we are all fearsome, strong, and deserving of LOVE.

How the Cupid's 2021 Challenge works


Get your mates together and sign-up for the Cupid's Undie Run 2021 Challenge, from 14 - 28 February. It's more fun taking your pants off for charity together! And don't forget to order your Cupid's gear for Challenge No. 1 taking place on "Undie Sunday", what we're affectionately calling Valentine's Day!

Complete the challenges

Cupid has set you some Cheeky Challenges. Some are more challenging than others, some you will know beforehand, some will be secret – otherwise, it wouldn't challenging! The more challenges you complete the more chances you have to WIN and raise funds for NF!

Join us for a Sunday Session

To celebrate the end of a "challenging" fortnight, join us for a virtual Sunday Session on 28 February from the comfort of your own lounge. There'll be Cupid's cocktails, cheeky comedy, music, and NF Heroes of course. Plus we'll announce winners of some amazing prizes – you might even see your face on the big screen!

No need to feel shy. We are all friends here.



No worries! Here is how to set up a team page with friends.
