What is the DIRTY DUO?
Being mountain bikers and trail runners, we want to share what living and playing on the rugged North Shore trails is all about!! This scenic trail race will challenge beginners as well as extreme athletes. Here are the five options:
Run 25 km,
Run 15 km,
Run 50 km ultra (first of the Montrail Ultrarunning Series),
Do a relay; one runs and the other rides,
Do it all! Go solo and do both the 25 km run and 30 km bike,
Mountain bike 30 km only.
Note: You do not need to run and bike; you can choose one event!
