On September 11, 2023 Notre Dame DuncanHall hosted its fifth annual ND110, an event honoring first responders. ND110 is Duncan Hall's newest signature charity event that honors our first responders. Participants ran up the equivalent of 110 flights of stairs in Notre Dame Stadium in memory of the 110 floors of the World Trade Center buildings destroyed on 9/11. Proceeds from the event benefitted HEART 9/11. An estimated 847 participants climbed the stairs. Thank You UND for honoring our promise to "Never Forget".
