Get ready for the 27th annual Ballwin Triathlon, a USAT-sanctioned event hosted by MSE Racing in partnership with the City of Ballwin, MO, featuring a 300-yard pool swim, 9-mile bike ride, and 3.4-mile run. This beloved race typically sells out each year, so register early to secure your spot! If you're seeking an extra challenge, consider the Double Triathlon option, where you'll complete the entire course twice, with the second swim starting with a lap around North Pointe's lazy river.
