Event Partners​​
On-Course Nutrition by Olway™
​
We considered offering burgers for in-race nutrition on Sunday but instead we’ve partnered with Olway™. Founded in Collingwood, Olway™ is a performance nutrition brand focused on designing formulas for everyday athletes and pricing them 30% less than the industry average so they can afford to use them in every session. With the heat imminent, their Performance Drink Mix will be key to maintaining energy levels and staying hydrated on course.
