Dirty Duo : Trail Whisperer Race Series

Dirty Duo takes place at Inter River Park in North Vancouver on Saturday, March 20, 2027. The event offers multiple trail distances and a relay, all starting and finishing at the park near the entrance to the Lower Seymour Conservation Reserve.

The event distances include:

  • 15K
  • 25K
  • 35K
  • 15K relay each runner completes 15K

Courses run on North Shore trails with a mix of groomed and technical terrain. Routes feature climbs, switchbacks, river crossings and downhill sections; the 35K uses a two-loop format. Courses are marked with pink and black flagging tape, pink flags, signs and marshals at key intersections. Elevation profiles and route maps are provided for each distance, and GPX and PDF downloads are available.

Aid stations are located on each course and supply water, electrolyte drink, gels, chips, blocks or chews, cookies and other treats; first aid and hygiene supplies are available at every aid station. The event is cup-less; racers must provide their own cup or bottle at aid stations and the finish.

There is no mandatory gear list, but runners are encouraged to carry hydration, fuel and extra clothing. Package pickup is available Friday, March 19 at the Running Room in North Vancouver and on race day at the start. Awards are given to the top three in each gender category for each distance and every finisher receives a medal. Parking is available at Inter River Park and Capilano University; carpooling is recommended. Visit the organization's website for the most recent information.
