Success! Well, sort of. While I completed the climb in 58 minutes, which was less than my target of 1 hour, The Grind was closed for maintenance so I climbed the adjacent BCMC instead. While the “Grouse Grind” climbs up the side of Grouse Mountain over 2.9 kilometers, the BCMC climbs up the side of Grouse over 3.4 kilometers. To put it another way, the trails start at the same place (parking lot D on Grouse) and finish at the same place (the top of the Grouse mountain) but the BCMC is about 20% longer. This means the slope is less steep: to be precise, the slope is a 25% gradient on the BCMC instead of a 29% gradient on the Grind.
