Fiesta de Mayo 5k

The Fiesta de Mayo 5K, set for Sunday, May 3, 2026, invites runners and walkers to experience a vibrant morning in the picturesque setting of Webster Groves, MO. This event carries a rich legacy, marking its 4th annual return as the Fiesta de Mayo, continuing the tradition of the long-standing "Race to Cure Lymphoma." Organized by Battling Together, all proceeds directly benefit Blood Cancer United (formerly the Leukemia & Lymphoma Society) in their vital mission to find a cure for blood cancers. Participants can anticipate a professionally timed 5K course that winds through the stately streets of Webster Groves, offering a scenic journey for all fitness levels.

Runners will begin and end their journey in Downtown Webster Groves, with the Upper Municipal Parking Lot at 20 Allen Avenue serving as a central hub for race activities. Typical race day conditions in early May feature comfortable highs around 72°F and lows around 52°F, with a relatively low 19% chance of precipitation, creating an enjoyable environment for hitting the pavement. Beyond the course, the Fiesta de Mayo 5K stands out for its lively post-race celebration. Finishers can cool down with refreshing Kona Ice snow cones or toast their accomplishment with a signature margarita (for those 21 and over).

Each registration for this impactful 5K includes a custom Fiesta de Mayo Tee and professional chip timing, ensuring accurate results. Youth finishers (16 and under) will also receive commemorative medals, making it a memorable event for the whole family. Join a community dedicated to a cause, enjoying a scenic run and a festive atmosphere, all while supporting the fight against blood cancers.
