About this race
The 27th annual Ballwin Triathlon fills up quickly. It features a pool swim, bike, and run. This year, the Double Triathlon is back for those looking for a greater challenge. You'll complete the course, then head back to the pool for a second round, starting with a lap around North Pointe’s lazy river.
