Two marathon greats entering their twilight years will race each other in the New York City Marathon for the first time this Sunday

Two young New Yorkers who overcame traumatic brain injuries — including one who had to relearn how to walk — are using their new lease on life to run in Sunday’s city marathon.

Queens-native hip-hop icon and Drink Champs host N.O.R.E. — real name Victor Santiago Jr — will run his first marathon Sunday with his Run Champs run crew. The “Oye Mi Canto” rapper, 48, has been eagerly counting down the days to race day on Instagram.
