Lee Ann Yanni -- who suffered major injuries in the 2013 Boston Marathon Bombing -- is returning to course on Monday to run 26.2 miles ... all to raise money for military families in need.
Yanni was a spectator at the 2013 marathon when shrapnel from one of the bombs hit her leg causing broken bones, severed nerves and other major injuries.
But, Yanni is a beast -- and just 6 months later, she completed the Chicago Marathon in 5 hours, 43 minutes. Amazing!
She's since completed the Boston Marathon TWICE -- once in 2014 and again in 2015.
