Key course features to know before comparing this race:

• A midnight start at North Bannister and a night climb to the high ground of the range
• Mount Cooke, where 100-mile runners tear a page from a book of affirmations to show at the finish
• Mossy granite and open wandoo woodland at first light
• Rocky singletrack through jarrah and marri forest and dry creek beds
• The Feral Village at the Perth Hills Discovery Centre, passed at 124.7 km before the out-and-back to Kalamunda

Bibbulmun Track singletrack through jarrah, marri and wandoo forest, with granite, dry creek beds and rocky sections. The track is marked with the yellow Waugal; the organizer warns runners not to follow the blue Munda Biddi bike trail markers. Runners must carry the course GPX on the Gaia Maps app, or the paper Map 1 of the Bibbulmun Track (Kalamunda to North Bannister).

The organizer’s November averages are 9–27°C (48–81°F) at North Bannister and 13–26°C (55–79°F) at Mundaring, with about 19 mm and 23 mm (0.7 and 0.9 in) of rain. Its race-week forecast for 2026 gave about 10°C (50°F) at the midnight start, then 13–29°C (55–84°F), sunny and breezy, on Saturday and 13–27°C (55–81°F) on Sunday at Mundaring, and warned of a hot, dry weekend.

Entry & Logistics

Why This Race Matters

Ultra Series Australia, which also runs Delirious WEST, holds the Feral Pig Ultra on the first weekend of November on the Bibbulmun Track in the Perth Hills. The Bibbulmun Track runs about 1,000 km (621 mi) from Kalamunda to Albany. The 100 Miler covers its northern end, from North Bannister to Mundaring, and then runs out to Kalamunda and back. The organizer’s results archive starts in 2016, when the longest race was 50 miles; the first 100-mile results are from 2017. The 2023 event was canceled because of bushfires and firefighting near the course, and the 2019 results file lists only 50 km and 23 km races. The 100 Miler is listed with ITRA and counts toward the UTMB Index in the 100M category. Michael Hooker holds the men’s record, 18:28:42 from 2020, and Jen Millum the women’s, 24:31:10 from 2018.

Preparing for a Race Like Feral Pig Ultra 100 Miler

The fixed-distance race guide covers the format as a whole. These guides go deeper:

• Walking strategy for ultramarathons: When and how to walk by terrain, effort and cutoffs.
• Crew and aid-station strategy: Crew tables, aid stops, drop bags and runner preferences.
• Hydration and sodium for ultramarathons: Fluid, sodium, thirst, sweat rate and hyponatremia risk.
• Tapering for ultramarathons: Plan the taper and race week around your own recovery.

Best Fit

• Runners who want a crewed, pacer-friendly 100-miler in the Perth Hills
• Runners comfortable starting a 100-miler in the dark at midnight
• Runners with experience on rugged trails in hot conditions

Planning Notes

• Train for terrain-specific fatigue. Technical trails and mountain courses demand downhill durability, hiking efficiency, and reliable night lighting.
• The directory does not mark this as having simpler logistics. Confirm qualification, terrain, support, registration, medical, and withdrawal requirements before planning around it.
• Heat: the organizer warns that hot days are common in November, and the 2026 forecast reached 29°C (84°F)
• No crew access for 40.5 km (25.2 mi) between Mt Dale and the Discovery Centre
• A 30.8 km (19.2 mi) stretch from Sullivan Rock to Brookton Hwy with only the unmanned Canning water stop
• Missing mandatory gear at a random check means disqualification
• The hi-vis vest goes over the pack from sunset to sunrise
