If you were horrified by the Boston Marathon bombings and felt helpless not knowing how you could help, now you can — provided you can run or walk, and have an hour free this Saturday morning.

The Hard Core Runners club, a nonprofit organization comprised of, yes, runners, has organized a fundraising fun run (or walk) this Saturday morning (April 20) to raise money for the victims of the Boston Marathon bombings. The 2.62-mile event — a distance chosen because that is one-tenth of a marathon — will begin at 9 a.m. at Sarg Hubbard Park on the Yakima Greenway.

Members of the Hard Core Runners will collect tax-deductible donations starting at 8 a.m.; the organization will forward the donations to OneFundBoston, a charity set up by the Boston business community to support victims of the bombings.

Knowing how many people want to support those victims, participants in the event — in addition to being able to donate themselves — can augment those donations by getting pledges from friends and co-workers. (Just get them to pay their pledge donation in advance; that way you can turn those donations in on Saturday morning. We’re fairly certain they’ll trust you to finish the course, and that they won’t mind even if you don’t.)

A digital clock will be running, but this is a fun run/walk with no formal results. The club will serve refreshments afterward. For more information, check the club’s website (it should be posted there by late Thursday afternoon) or call Frank Purdy at 961-9769.
