Join us for Philadelphia Marathon Weekend and fundraise for the Maternal Alloimmunization Foundation. When you run with Team MAF, we’ll cover your race entry fee so you can focus on what matters most: raising awareness, supporting families and helping protect babies affected by maternal alloimmunization and HDFN.

Team MAF runners receive a special race shirt, additional swag as fundraising milestones are reached, access to a supportive community of alloimmunized families and all the official benefits of race weekend.

Together, we’re turning each mile into something bigger: awareness, support and hope for moms and babies.
