The race takes over the indoor track from 8-11 a.m. on Feb. 15 at Saint Xavier's Shannon Center at 3700 W. 103rd St. in Mount Greenwood.
Athletes begin with 15 minutes of running or walking, followed by 15 minutes on a stationary bike and concluding with another 15 minutes of running or walking.
Organizers gives contestants a five-minute break between activities. Winners are judged by the combined number of laps on the eighth-mile track and number of miles completed on either a recumbent or upright bike.
Participants must be 18 or older. It costs $25 to compete in the duathlon, with discounts are available for Saint Xavier students and staff. All entrants will received a short-sleeve T-shirt and goody bag on race day.
The early time slots fill up quickly, but the event has never sold out in its 10-year history.
The top finishers typically average 6 miles on the stationary bike and run at about a five-minute-per-mile pace. Medals will be given to the overall top three males and females.
