The Challenge mascot Leuk the Duck has provided support and education to kids with cancer and their families for almost 30 years. In the spirit of Childhood Cancer Awareness Month, September will be your chance to learn a little more about who Leuk is and what he knows.

If you have any stories with Leuk that you’d like to share, please do and tag @challengecancer and @leuktheduck with the hashtag #LeukInSeptember.

Stay tuned to see more of Leuk and most of all, go gold this September for kids with cancer!
