Directions & Parking
The Armagh S. Price Park/Brockville Rowing Club site is located right downtown at the corner of Water Street East and Ferry Street on the shores of the St. Lawrence River. Parking is available near the site and on side streets north of King Street. 

750m and 1500m Swim
The swims are in the St. Lawrence River. Both swims begin at the boat ramp adjacent to the T-Zone with a deep water start. The swim course is a triangle of 750m, which the Olympic Triathlon participants swim twice. 

The exit ramp is a concrete slab that allows participants to walk out of the water. Although the we have made our best efforts to pressure wash the ramp it may be slippery so use caution when entering and exiting. 

200m Swim
The 200m swim is on a triangle course near shore. 

20.7K Bike Course
The 20.7K bike is an out and back course. Cyclists exit the transition zone onto Water Street, which is closed to all but local traffic during the event (first and last 500m). They head East on Water Street to Ford Street where they turn left and go up a short steep hill to King Street. They turn right onto King Street East (Highway 2), and proceed to the turn around. 

40.2K Bike Course
The 40.2K cyclists do two loops of the 20.7K course.  However the turn around point is at the top of the hill. DO NOT come all the way back to transition after your first loop. 

Things to Remember About Our Bike Course
The route is not closed to traffic except for the 1st and last 500m. There are difficult 90 degree corners on Ford Street, at King Street,  and Water Street due to the nature of the course and unpredictability of in town motor vehicle traffic. You must NOT use your aero bars until you are east of the intersection of North Augusta and King Street. This section is controlled by marshals and police but cyclists should proceed with caution. Using your aero bars on this section of the course will result in DQ.

Duathlon First Run (2.5K):
From the start line at Blockhouse Island Parkway  and Water Street runners will do one loop of Blockhouse Island and then head through the rail tunnel to the turn around back through the tunnel. Once they exit the tunnel they will head directly to the T-Zone.

Sprint and Duathlon Second Run (5K):
Starting from either the T-Zone or the start line at Blockhouse Island Parkway and Water Street runners will do one loop of Blockhouse Island and then head through the rail tunnel until they reach the turn around and head back into the tunnel. Once they exit the tunnel they will complete another loop or go to the finish line. This a 2 loop course.

Olympic Triathlon and Second Duathlon Run (10K):
Starting from either the T-Zone or the start line at Blockhouse Island Parkway and Water Street runners will do one loop of Blockhouse Island and then head through the rail tunnel until they reach the turn around and head back into the tunnel. Once they exit the tunnel they willcomplete another loop or go to the finish line. This a 4 loop course.

Try A Tri (2.5K):
Runners will do one loop of Blockhouse Island and then head through the rail tunnel to the turn around and back through the tunnel. Once they exit the tunnel they will head to the T-Zone.
