Longest off-road cycle track opens in WA WESTERN Australia can now boast having the world's longest off-road continuous cycle track, following the completion of the 1000km Munda Biddi Trail, east of Perth. The trail was officially opened at the Festival of Cycling in Mundaring on Sunday where the first cyclists to complete the newly extended trail crossed the finish line of the Munda Biddi Epic 1000 that began three weeks ago in Albany, in the state's south. The WA government estimated more than 20,000 international, interstate and local cyclists used the Munda Biddi every year, and that number was set to grow with the completion of the trail. The Munda Biddi Trail now extends from Mundaring to Albany and passes Jarrahdale, Dwellingup, Collie, Donnybrook, Boyanup, Nannup, Manjimup, Quinninup, Pemberton, Walpole and Denmark, as well as other smaller communities. Munda Biddi means "path through the forest" in the Noongar language. Construction on the trail, which was 12 years in the making, also involved prison crews working on some parts of the project.
