The commissioner had been planning on running this year’s Boston Marathon as his 50th race, but pulled out after the Brussels attacks raised security concerns. He said he loves the Boston Marathon, but doesn’t regret that it wasn’t his 50th.

“As much as I would’ve loved to run Boston, I just couldn’t do it,” Evans said. “The safety of the city always comes first. Running is a passion for me but keeping people safe is always my top priority.”

Evans runs marathons on Team MR8, the Martin Richard Foundation’s running team, created to honor the memory of the youngest victim of the Boston Marathon bombings.

“I’m very proud that the family includes me in running in their club,” Evans told Runner’s World in February. “It’s a good way to remember Martin. I think he’ll always be special in this city.”
