A beautiful, picturesque course that is also both flat and fast

The 10k and Half Marathon will start together. Both races start and finish in the White Water Centre, opening with the 10k lap and approaching the finish area, the Half Marathon cuts away to complete a complete lap of the White Water rapids before heading back in to the Regional Park for a second lap, including a short out-and-back section to ensure the course distance is accurate.



And after completing your distance, you will be congratulated with a custom event medal and goodies at the finish line.

The event will also be chip timed so you will get an accurate time for your race

After completing the event we invite you to join us on the terrace overlooking the White Water Centre, listen to Live Music and watch the sun go down.
