A new triathlon is coming to Mankato this summer geared toward kids. The Hy-Vee IronKids Triathlon will make its debut in Mankato on August 3. It will be held at Spring Lake Park and will follow the same swim-bike-run format as an adult tri, but the distances will be adjusted for the age group. The event is open to kids ages 6 to 15. In total the Hy-Vee IronKids Triathlon Midwest Series includes 20 youth triathlons, Mankato is a new site this year.
