More than 500 triathletes will descend upon Wolf Lake Memorial Park for the annual Leon's Triathlon, set to begin at 8:00 a.m. on Sunday, June 1. Leon's Triathlon, known as the "world's fastest triathlon," is a nationally broadcasted Olympic-distance race.

During the Olympic-distance race, athletes will swim .09 miles, bike 24.8 miles and run 6.2 miles. New in 2014, athletes have the option to participate in a sprint distance race, which includes a .465-mile swim, 12.5-mile biking portion and a 3.1-mile running portion. Registration is still open, and costs $165 for Olympic individual, $130 for sprint individual, $290 for an Olympic relay team and $200 for a sprint relay team. For those wishing to participate in the team challenge, a group of five to 10 athletes where the top five times are used to determine winners, registration is $165 per team member.

Demo Day, an interactive race expo, is from 10 a.m. until 5 p.m. on Saturday, May 31. The event will showcase the latest technology in triathlon gear. Attendees will be able to try on running shoes and wet suits and test ride bicycles. The event will also host an equipment drive supporting Tri-Masters, a not-for-profit organization that empowers at-risk children through triathlons in order to teach life lessons. Demo Day is free to attend and open to the public.
