From the Organizer
The Gillie Girl Sprint Triathlon is located approximately 2 miles off Route 5 near West Hill Golf Course at the Intersection of Ike Dixon Road between Sand Road and Gillie Brook Road. The swim is 1/2 mile (2 loops) in a natural, spring fed Gillie Lake, a relatively flat 15 mile bike course and a spectator friendly 5k run to round out the course. This is a great event for all women - first time racers, seasoned triathletes and relay teams. Come join the 13th Annual Gillie Girl Sprint Triathlon, it's a spectator friendly course, and family atmosphere.
The 2024 edition will include the sprint triathlon (individual and relay) and Aquabike (swim, bike). This race category is popular with those not ready to run the 5k stance for whatever reason. Racers will swim and ride the same courses as those in the triathlon, but when you are done biking, you are finished with the race. We welcome you to the race infield to enjoy food and drink and cheer on your friends and/or family still on the racecourse!
