Advocate Good Shepherd Fitness Center in Lake Barrington held its second-annual indoor triathlon Sunday.
The event was held in memory of Jon Carlino, a 29-year-old personal trainer from Algonquin who died unexpectedly last summer.
The race format included a 10-minute swim, followed by a 10-minute transition and a 20-minute bike ride on spin bikes, followed by a 5 minute transition and a 15-minute run on the center's track.
Unlike traditional triathlons, a racer's finish placement is calculated by total distance swam, ridden and run instead of by lowest time. Participants were assigned someone to count their swimming and running lap and to document the miles ridden on the bike.
