Since 2010, the Graniteman Triathlon in Big Lake has grown to be one of Minnesota’s favorite triathlons.

Graniteman Big Lake is the last race in the Graniteman Triathlon Series that begins in June with the Buffalo Triathlon. Our Big Lake race takes place at Lakeside Park located right on HWY 10 and is just 30 minutes from the Twin Cities and St. Cloud.

Offering both sprint and olympic distances, you will swim in the clean and clear waters of Big Lake, get your seasons PR on one of the flattest and fastest bike rides in the state, and enjoy a lakeside run that starts and finishes in the park.  There is also a new playground for the kids, great music, and plenty of food.

Staging for the swim will be at the Lakeside Park beach. Please line up and group together as instructed with your wave. The swim will be a triangular course around the swim area at Lakeside Park.  Markers will be added or adjusted for distance adjustments. Each racer will be provided with a swim cap that MUST BE WORN.  There will be lifeguards and boaters along the course if you need to rest.  However, do not move forward while resting on a flotation device or you will be disqualified.  If you are in distress, remove your swim cap and wave it in the air and a lifeguard will come assist you.  If a lifeguard or boater thinks you are struggling and has concern for your safety, they do have the authority to pull you from the race.  Coming out of the water, run the chute to the transition area.
