TAMPA - Running stores across the country are starting to come together to honor the victims of the bombings in Boston, and organize a fundraising run Monday night. The campaign is called “Runners for Boston,” and includes a memorial 3-mile run at each participating store at 6:30 p.m. Monday. The first mile will be run in silence, along with runners across the country. The overall project is being organized by the Independent Running Retailers Association. In Tampa, one participating store is FitNiche, with runs starting from their location in Hyde Park Village. The Wesley Chapel store in Pasco County is also participating. The stores will also sell memorial T-shirts for $20, with all proceeds going to onefundboston.org, an umbrella fund established by the Massachusetts governor and Boston mayor. “On Monday, we will become one running community coming together to support Boston and its victims,” said FitNiche owner Rich Wills in a letter to his customers.
