By participating in IronMatt events, you’ll join a growing community of people who want all children to swim, bike, and run until they’re 70, not 7. Find the events and fundraisers you’d like to participate in or add your own date to the calendar!
IronMatt Gala: Dinner & Auction
September 18, 2025, Ziegfeld Ballroom 141 West 54 Street, New York, NY
IronMatt has been a charity partner of the NYC Marathon since 2019.
This 26.2-mile marathon will take runners through all five boroughs of New York City, and they’re asking for your sponsorship. All funds raised by Team IronMatt will be used to support the IronMatt mission.
Giving Tuesday — the Tuesday after Black Friday and Cyber Monday — is a day of giving back. Let’s give the gift of life to children battling pediatric brain turmors.
Basketball fans, March Mattness is your opportunity to turn your favorite sporting event into an opportunity to help IronKids everywhere. Enjoy a beer pong tournament, live music, and a rousing good time!
Please note, event tickets and auction items are “goods and services” for tax purposes. They cannot be purchased through a giving account and must be paid out of pocket.
