6 Inch Trail Marathon
Sunday 20th December 2026
The 6 Inch is a 47km hilly (about 900m ascent including a 140m in 1.5km ascent) trail running race held on the Munda Biddi trail, from North Dandalup to Dwellingup about 1 hours' drive south of Perth, Western Australia.
This race is the brainchild of David Kennedy, who came up with this idea after hearing about the legendary Six-foot track 45km in the Blue Mountains of New South Wales, Australia.
This year's 6 Inch Trail Marathon is being held on Sunday 20 December 2026.
