Where 6 Inch Trail Marathon 23km starts and finishes
6 Inch Trail Marathon 23km starts at Goldmine Hill, North Dandalup (start) to Dwellingup (finish). 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.
Full 6 Inch Trail Marathon 23km Route Breakdown
The 6 Inch Trail Marathon follows a 46‑kilometre segment of the renowned Munda Biddi Trail, one of the world’s longest off‑road paths. The race begins at Goldmine Hill in North Dandalup, winding through dense jarrah and karri forest, under the canopy of towering eucalyptus trees that provide natural shade. Runners will tackle a mix of gentle undulations, creek crossings and occasional rocky sections, all on well‑maintained wide trail tracks designed for a steady rhythm. The course finishes in the historic timber town of Dwellingup, where participants are greeted by the community’s warm hospitality. With a half‑marathon option of 23km starting at the Munda Biddi crossing on Nth Spur Rd, the event offers both a challenging ultra‑distance and a more accessible distance for trail runners.

Training Strategy for 6 Inch Trail Marathon 23km
6-10 weeks is a solid window for a 14.29-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 Goldmine Hill, North Dandalup (start) to Dwellingup (finish) 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.
14.29-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.
