The Gladstone Community Center is hosting its annual Shamrock Shake-up Indoor Triathlon on Saturday, March 14. This triathlon is acceptable for beginners as well as experienced athletes, and it all takes place inside the center, 6901 N. Holmes St.

During this triathlon, performance is measured by distance covered in each of the three timed legs. Each athlete will swim 10-minutes in the competition pool, ride 30 minutes on the spinner stationary bikes and finish with a 20-minute run on the center’s indoor track. The more distance a participant covers the higher they will rank.

Sticking with the annual St. Patrick’s theme, the 10-minute swim will be called Quell the Tide; the bike ride, Survive the Ride; and Conquer the Stride for the run.

Registration is open until March 8. The cost is $30 for community center members and $35 for nonmembers.
