The 2013 Spring Fling Indoor Triathlon is set for Sunday, March 17, at the Newton YMCA.

The race day will begin at 8 a.m. with individuals competing in three events — 15 minutes of swimming laps in the Y’s indoor pool, 15 minutes of cycling on a bike and 15 minutes of running on a treadmill. Each individual will be placed based on distance accumulated in each event during their 15 minutes of competition.

“This will be a fun day of competition for all ages and levels of athleticism,” said Sue Field, YMCA fitness director. “The event is really an introduction to the sport of competing in triathlons and is a great warm up for the Y’s Summer Daze Tri in May.”
