Each year since 2008, the number of seniors running the Vancouver half- and full-marathon has increased, nearly doubling for both septuagenarian men and women.

To "recognize and reward" these competitors, the BMO Vancouver Marathon introduced new age categories for the 2013 race. Runners aged 70 and over were previously grouped in one running class but will now be grouped by five-year increments from 76-80, 81-85, 86-90, 91-95 and 96-100.

Eleven women and 40 men registered for the 70-and-over age group in 2008, and the numbers increased every year since. In 2012, 36 women and 74 men in that category ran the 41st installment of the scenic Vancouver race.

Senior runners are an inspiration for all racers, said Charlene Krepiakevich, the executive director of the Vancouver International Marathon Society. "We really wanted to distinguish their achievements and continue to encourage all runners to keep a healthy lifestyle."
