These Dedicated Runners Have Done Every La Marathon For Nearly 4 Decades

They have run through heartache and grief, battling illnesses and injuries as their bodies have aged. Some are now using wheelchairs, including the oldest who is 87.

Despite it all, the Los Angeles Marathon's Legacy Runners have stuck to their mission: finish the race.

On Sunday, the group of 92 marathoners, including 10 women, marked their 40th LA Marathon, participating in the 26.2-mile 42.2-kilometer race every year since the city's iconic event began in 1986.

"We're legacy runners, we just don't know when to quit," 77-year-old Lou Briones said.

Briones even has finished the race on crutches after surgery. Since getting both knees replaced, he walks the race.
