Why We Run:
The TANGO2 RESEARCH FOUNDATION was a lifeline for Megan Galland, who faced her first health crisis at just six months old during a family trip. Initially misdiagnosed, Megan eventually received answers thanks to the tireless work of the TANGO2 FOUNDATION. Now, we're running to give that same hope to other families.
