Florissant St. Patrick's Day 5K Run
About this race
The City of Florissant is extremely proud of our heritage- Founded by French, Built by German, Run by Irish. We were the initial location for the St. Patrick's Day Parade, and we are beyond excited to bring an event such as this back to great area. Florissant is truly a city of festivals, and we are looking to build on that rich tradition by hosting a St. Patrick's Day Parade, Festival and 5K. Please join us for our 5K Run, taking a tour through scenic Old Town Florissant showcasing our beautiful history and providing a bit of a challenge for our runners!
