Event Overview
The Roller Coaster Run is a mountain running event held in the Dandenong Ranges, starting and finishing at Kalorama Memorial Reserve in Kalorama, Victoria. The 2026 edition is scheduled for Saturday 17 October and offers three main distances: 46km, 23km and 12.4km. Established in 2012, it is delivered by SingleTrack Events and uses a shared event village for all races, with different start times across the day.
What the Course Demands
Across the 46km, 23km and 12.4km races, the course features repeated steep climbing and sustained descending, with frequent changes in gradient that can disrupt rhythm. The 23km course lists 1100m+ elevation gain, while the 46km double loop totals 2200m+- by completing the loop in both directions. Key segments include a long steep climb on Observatory Track and another steep climb after Doongalla.
Who This Event Suits Best
This event suits runners who are comfortable with prolonged climbs and controlled descending, and who want a course that rewards steady effort and good pacing discipline. The 12.4km option can work for newer trail runners looking for a shorter challenge, while the 23km suits experienced runners wanting a substantial vertical day. The 46km is best for athletes prepared for an ultra-distance double loop and tighter cut-offs.
