Duluth, MN (NNCNOW.com) - A surprise, or rather, a miracle for a Duluth woman who had been training for Grandma's Half-Marathon.

33-year-old Trish Staine gave birth to Mira, short for Miracle, on Monday a day after she started feeling some back stiffness after running abut nine miles.

Staine says she didn't know she was pregnant until minutes before she gave birth!

Mira weighed 6 pounds, 6 ounces.

John Staine, the father, says his wife didn't gain any weight not show any other symptoms of pregnancy.
