C-WISE DWELLINGUP 100
The Dwellingup 100 is an event rich in history, beginning in 2009 and having seen over 10,000 participants take part. It has attracted riders of all ages and abilities, including world champions, national champions, prominent WA riders, local mountain bike fanatics and even those newly introduced to the sport.
Below is a snapshot of the event over the years, a history we are proud of and one we look forward to adding to year on year.
Mighty Jarrah Trail Run
The Mighty Jarrah Trail Run was initially developed as a sister event to the Dwellingup 100 but it has since become an event of it’s own, one which has seen it develop into one of WA’s largest trail running events. Over the years, 1,600 participants have taken part in the event, including those of all ages and abilities.
Below is a snapshot of the event over the years, a history we are equally proud of and one we look forward to adding to year on year.

2018
The year the event almost didn’t go ahead due to the closure of TriEvents, the founding company and previous event managers. Much like the beloved mountain bike race, the Tucknott family and John Carney rallied together to make it happen and what an event is was. This saw just under 250 runners take to the tracks for what was renamed the Dwellingup Trail Run.

2023
With its sister event Dwellingup 100 hosting the UCI championships on the Saturday, the Might Jarrah Trail Run was moved to the Sunday along with the two shorter D100 events. This created a unique opportunity for those doing a longer distance on Saturday to also have a run on Sunday as well. It also meant that we could show off the amazing running trails on offer to an international audience.
2024
With Sunny Skies and good vibes the Mighty Jarrah Trail Run was a Huge Success! with over 460 runners taking to the beautiful trails of Dwellingup!
