The Hardest 100 Km Trail Run Anywhere.

This run began as a love of the North Shore mountain trails in North Vancouver, British Columbia, Canada, and as a challenge to those looking for more than the usual ultra event. Very few have accomplished it before (7 in 2005, 6 in 2006, 4 in 2007, 8 in 2008, 2 in 2009, 8 in 2010, 9 in 2011, 7 in 2012 - some of these are repeat offenders). And now the time has come to challenge it once again in 2013.

This is a serious event for individuals with a pure quest to experience the love of the trail at its most challenging. If you’re only ready for part of the run, come along and support the ultra distance runners (50 km and beyond). Begin at any quarter mark of the trail and complete as many quarters as you wish.

If you have been wanting to try a night run this is your chance to see just what the experience is like. Expect the section from Cleveland Dam to Deep Cove to be run through the night with the slowest runner taking about 9 hours by that time. You will be asked to join up with a group as they pass through each section. There may be one group or more but we want you to stay together with at least one other runner when possible.


The Vancouver 100 (formerly The Double) is perhaps the hardest 100 Km trail run anywhere. This is a very technical course with monster hills to climb and descend and with amazing views to match. Conditions on race day are expected to be favourable although there will likely still be snow on much of the upper sections from Km 32 to Km 40 on the way out.

The Vancouver 100 is designed to test the best long distance trail runner. Expect your time to be longer on this course than any other 100 Km event you will have previously completed. Participants should be confident in their uphill and downhill running abilities on rocky, rooty, muddy, snowy and potentially treacherous trails.
