Course DNA
The Course
Guzzler Ultra runs 100 km through Australia. +18,980 ft gain and -18,980 ft loss. Surfaces skew 75% trail / 20% dirt road / 5% paved. Heat, bush tracks, and steep coastal or alpine climbs. High point near 1,690 ft. Low near 52 ft. July temps run 45°F to 90°F. The course rewards patience early and punishes rushed descents after mile 31.
The Work
Train for 18,980 feet of climbing across 100 km. Back-to-back long runs on trail. Practice power-hiking grades above 15 percent. 24 hours total means limited margin: rehearse fueling every 45 to 60 minutes and downhill eccentric work weekly. Technicality 5/10. Build a block that simulates the crux near mile 40.
Kit
July in Australia: plan for 45°F to 90°F. Mandatory shell if rain is in forecast. Headlamp with spare batteries if 24 hours pushes past dark. Poles help on sustained climbs above mile 16. Vest capacity for 2 liters minimum. Shoes matched to 75% trail: lugs for mud, rock plate if the course turns technical after mile 31.
Race Day
Hold effort through mile 16. The field often splits on the first big climb after mile 31. Heat, bush tracks, and steep coastal or alpine climbs near mile 40 is where time is won or lost. Walk the steep pinches. Run the flats and gentle downhills. Crew at major aids: socks, calories, ice if hot. Transitions under 5 minutes when possible. Final third is 21 miles of fatigue management. Finish with reserve for the last descent.
