No, that's not a zipline across Capilano Lake! Just a GPS data error. Wish I knew how to edit it out. So the total distance is too high. See a similar hike: https://www.gaiagps.com/datasummary/track/d9b4d76f02b0bd7625483f018867b88e/?layer=GaiaTopoRasterMeters Distance should be about 11km; pace about 33min/km; ascent & descent about 40m each less than shown here.
