The Illumin8 Challenge 31.5km starts at Avondale University, 582 Freemans Dr, Cooranbong NSW 2265. We haven't been able to place those on a map accurately enough to show one — a pin in the wrong place is worse than no pin.
These are the start and finish points, not the route. Verus doesn't hold course files for this race, and drawing a line between two pins would be a guess you might end up training on.

Training Strategy for The Illumin8 Challenge 31.5km
6-10 weeks is a solid window for a 19.57-mile race. Combine a weekly long run with threshold work so you can hold pace over the full distance.
This is a largely flat course, so most of your long runs can mirror that — flat and steady, building time on feet rather than hill strength.
Ease off mileage in the final week, keeping a couple of short, sharp race-pace efforts to stay fresh. Arrive at Avondale University, 582 Freemans Dr, Cooranbong NSW 2265 fresh, energized, and primed — not fit, fresh.
Lock in your target pace using the interactive splits calculator below — no official pacers are confirmed for this event, so a pace band on your watch is the more reliable option.
Test your race-day fuel and hydration plan on your long training runs, not for the first time on race day — check the Race Day Checklist below for what's actually on this course.
19.57-Mile Nutrition & Fueling Plan
A normal diet is fine. There is no need to carb-load for a race of this length.
Eat a carbohydrate-focused breakfast two to three hours before the start, and stick to something you've already tested in training rather than trying anything new.
Fluid at the on-course stations is usually enough; some runners take a single gel around the hour mark.
A mix of carbohydrate and protein in the hour or so after finishing supports recovery.
