About this race

In partnership with the City of Ballwin, MSE Racing is excited to host the iconic 27th annual Ballwin Triathlon. The USAT sanctioned Ballwin Triathlon is a 300 yard pool swim, 9 mile bike, and 3.4 mile run. This race is very popular and fills up to capacity almost every year. Be sure to secure your spot early.

IT'S BACK this year: the Double Triathlon. If you are looking for a greater challenge, here’s your opportunity! Participants will complete the Ballwin Triathlon course and then head back to the pool to complete the course a second time beginning with one lap around North Pointe’s lazy river.

For more information including, but not limited to race options, course maps, schedule of events, packet pickup/endurance expo, volunteer - signup, sponsorship info, parking, etc. Please visit - https://www.mseracing.com/ballwin-triathlon
