The Annual Mayor's Triathlon will begin in the west parking lot of Walnut Creek Lake and Recreation area and finish nearby on the walking trail. The Triathlon begins with a 500-meter open water staggered swim in Walnut Creek Lake. The second leg of the race is a TBA-mile bike ride on parts of the hard surface trail and scenic highways around Walnut Creek and Papillion-La Vista South High School. Lastly, a 3-mile run on the trail in Walnut Creek completes the Triathlon. A new bike course will be featured in 2018.
