Tens of thousands of participants crossed the 2016 Boston Marathon finish line Monday, many of them with crowds cheering.
But hours after the crowds left, one woman continued to push along to complete her 77th marathon.
At 6:30 Monday night, 72-year-old Fran Drozdz was just hitting "Heartbreak Hill."

She finally crossed the finish line at 8:45 p.m.
Drozdz qualified through Dana Farber Foundation and tried for three years to get on the team.
She ran in honor of her husband Stan, who is fighting cancer for the third time. He waited all day for her at the finish line and guided her through the grandstand to cross the finish.
Stan said he was concerned she was injured or had gotten lost and even ended up calling Boston Police.
He said, "She's 72 years old and she's down 77 marathons. I'm one year older and I've done no marathon, so of course I'm proud of her."
Fran Drozdz has completed a marathon in every state, but decided to do a second round of all of the states.
