Bloomsday's impact on the Spokane region is not limited to improved cardiovascular performance. The event results in a significant economic impact as well. In 2004, a study prepared for the Lilac Bloomsday Association by Gonzaga University students Dan Futrell and Luke Hallstone, with oversight by Professor Scott Bozman, showed a direct economic impact of $9,576,959.64.

The Bloomsday Economic Impact Study was an assignment for a Research Methods class at Gonzaga. The survey was conducted by 60 marketing students from Gonzaga's Jepson School of Business. 568 Bloomsday finishers and 202 spectators were interviewed near the runner statues in Riverfront Park immediately following the run. Study results were as follows:

Direct Economic Impact: $9,576,959.64
