What your entry includes
The course
Swim: 1.9 km one-lap swim in sheltered Penrith Lake at the Sydney International Regatta Centre. The rectangular course starts from a pontoon in front of the grandstand and exits at the warm-up lake boat ramp under the Olympic Bridge. Bike: 90 km two-lap course featuring views of the Blue Mountains and surrounding countryside. Cyclists loop around Penrith Whitewater Stadium, exit via McCarthys Ln onto Castlereagh Rd, passing Brooks Ln, Wilshire Rd, Jockbett Rd, and The Driftway. Smooth road surfaces allow for fast times despite technical turns. Run: Flat run course situated around the regatta centre precinct.
ROKA Swim Course - 1.9km
The one-lap swim takes place in the man-made, sheltered Penrith Lake, home to the 2000 Olympic Sydney International Regatta Centre (SIRC). The iconic and purpose-built facility caters nicely for athletes and supporting spectators, as the rectangular-shaped course starts in front of the grandstand, making it the perfect swim course for a nervous swimmer.
Once passing the grandstand again on the way back towards the swim finish, athletes will swim under the bridge, where they exit to Transition.
Pontoon Start: All age group & team athletes will start from a pontoon in the main competition lake. Athletes can either dive or slide into the water after crossing the start line/timing mat. Physically Challenged Open/Exhibition Division starts will remain as mass deep water starts.
Swim Course & Exit: The last 200m of the swim course will head under the iconic Olympic Bridge and athletes will exit directly into transition from the warm up lake boat ramp.
Wetsuits: A provisional wetsuit ruling will be posted at Athlete Check-In and Event Information on Saturday from 11am. The official wetsuit ruling will be announced race morning by the commentary team.
ZOOT Bike Course - 90km
Athletes will take in scenic views of the Blue Mountains and roll through the countryside on the two-lap Zoot bike course. Cyclists will exit transition along the regatta, where they'll turn left to loop around Penrith Whitewater Stadium. Once the loop is complete, athletes will exit the precinct via McCarthys Ln, turning left onto Castlereagh Rd. Athletes will continue along this road past the 15K mark and Godolphin Stables, where they'll then make a U-turn further along Castlereagh Rd.
After the U-turn, athletes will turn left entering Brooks Ln, where they'll pass the 30K mark along Wilshire Rd. Riders will then turn left onto Jockbett Rd, following onto The Driftway where two U-turns will take place. Athletes will then follow the same path back until a left turn onto Castlereagh Rd again, where riders will continue back to the precinct.
The second lap begins at the corner of Castlereagh Rd and McCarthy's Ln and finishes back along the regatta towards transition. Technical turns will allow for a challenge, however the smooth road surfaces will see fast course times as athletes head to the run course.
