Battling Together would like to present Fiesta de Mayo.  

We would like to thank all the hard work Gary and Linda Chatham have done towards raising awareness and funds for Leukemia and Lymphoma. The two of them started Race to Cure Lymphoma nearly 20 years ago. The Race to Cure Lymphoma carried two races, the Cinco K Mayo and The Flat as a Pancake.  

Our family has raced and volunteered in their races. And now we are grateful for the opportunity to continue their legacy, and keeping these races going. We share a similar cause towards raising money for a cure of Leukemia and Lymphoma.  We appreciate you helping us raise money for this important cause. Webster Groves will continue to be the location of the race, but under the new name Fiesta de Mayo.

If you have participated in any of the previous Race to Cure Lymphoma events, thanks for coming back! For those checking us out for the first time, you won't be disappointed! Fiesta de Mayo opens our race season with an exciting morning of running! You'll enjoy a scenic 5K course that wanders among the stately homes in beautiful Webster Groves then celebrate with a snow cone or refreshing margarita. After all of that running you'll be HOT and THIRSTY! 

****Please sign up by April 18 to ensure Fiesta de Mayo race shirt****
