Trail Description

Runners will experience Lakes, Reservoirs, Rivers, Streams, Water Races, Swing bridges, Bridges from Historic Tram Lines, A Western Town, Forestry, Wetlands, Board Walks Mountains and the Sea just to name a few things. This trail has been described by so many as the Most Scenic Mountain Bike Ride in New Zealand. Now you have the chance to run it.

This run is limited to 1,000 participants on the day, and will cater for the beginner through to the Elite Ultra Athlete looking to do their fastest time. The Trail is a Grade 2 Mountain Bike Ride and does give some good uphill climbs, with the finish a good downhill to the seafront finish in Hokitika.

3 Fantastic Runs on the West Coast Wilderness Trail, the 100km and 54km can be done as a Team of 2 or Individual. The 24km is an individual solo event.

    With the 100km start there will be locations around Greymouth that you will be able to view competitors. There are other spots along the trail to the Taramakau Bridge. Please be careful when stopping or crossing the State Highway if you are encouraging competitors.

    After the Taramakau River the next best place would be Kumara Main Street before they go back into the Bush and are out briefly at Loopline Road at the Reservoirs, then not until the Old Christchurch Road for 200 metres, then Lake Kaniere.

    We request that spectators do not go up Milltown Road towards Cowboy Paradise as the runners will be running on the shingle road and there are a number of blind corners throughout this section of the run.

    Then the best spot will be at the Finish on the Waterfront at Hokitika.
