Ryan Dempster
Getty ImagesFormer Red Sox pitcher Ryan Dempster spent his only major league season in Boston in 2013. That year and its aftermath inspired the Canadian baseball player to run 26.2 miles this Patriot’s Day. His first day as the winning pitcher for the Red Sox coincided with the day of the bombing, “and our team was part of something really special afterward with the city to rally around and trying to turn a tragedy around into triumph,” he told WBZ-TV’s Dan Roche. He’s running for the Lingzi Foundation, in honor of Lu Lingzi, a Boston University graduate student who was killed in the 2013 attack.

The Puerto Rican tennis star will be heading to London a week later, notching two World Marathon Majors back to back. Her goal is to complete all six majors. The multi-sport talent has said of her newfound love of running, “Running has given me a sense of purpose and plenty of goals to work towards. It’s the hobby I never knew I needed.”
