Course Description

The course will be impeccably well-marked on race day, in fact you’ll hardly go a full minute without seeing some form of course flagging.

If you use the information on this page for training runs, you do so at your own risk. As with any training run, you should head out prepared with typical trail running emergency supplies in the event you miss a turn or worse.

The following description is for informational purposes only and is not an accurate guide to be used for navigation. Any person who uses this to find their way around the course does so at their own risk. The race course will be well-marked with pin-flags, streamer tape, pylons, coreplast signage and placards on trail posts.

Start is located at Belcarra Regional Park, Sasamat Lake, White Pine Beach. Off the start we run along the beach a short stretch before turning to head up the paved path away from the beach. At the top of the pavement you hook a left and then follow this trail as it winds around Sasamat Lake, which will be on your left side. About halfway around the lake, you approach a bridge across the lake, which you take. At the end of that bridge you take a sharp right and go up a flight of stairs, then along some singletrack, and then up a second set of stairs. At the top of these stairs you find yourself at the entrance to Sasamat Lake. Turn left, proceed down the shoulder of the road about 100 meter, then cross the road, go past the yellow gate, and up the old gravel service road under the powerlines.

Follow this trail up, up, up. Just after the first view on your left of the Vancouver area, bear left on the trail. Follow the trail around the S curve to the Saddle, which is the location of Water Station #1.

At the water station, turn left and up onto the Diez Vista Trail. Follow the ridge past the viewpoints. After a rooty, rocky, trail up and then a very steep downhill, you will arrive on a gravel road, turn right. Follow this short section to its terminus around the corner and take the singletrack trail to the right.

At the next intersection stay to the left, go towards and then over the suspension bridge at North Beach on Buntzen Lake. Once across the suspension bridge you’ll do an out and back to the left, along the service road, to Aid Station #2.

After AS #2 head back the way you came, across the suspension bridge and then stay left again at the next intersection, now taking the Buntzen Lake Trail, on the west side of the lake.

Follow the Buntzen Lake Trail until you arrive at Pumphouse Road. Follow this gravel road until you can turn left onto the berm and the floating bridge which crosses the lake. Once across the lake, bear left. Follow the trail, turning left at the only intersection. Turn left again onto the Energy Trail. After 200m, turn right, still on the Energy Trail, and then left again in another 100m, still on the Energy Trail. Climb up, over and down the knoll, ending up at the Buntzen South Beach gazebo, Aid Station #3.

From AS#3, run across the lawn, past the washroom buildings and reconnect to the Buntzen Lake Trail along the east side of the lake, heading north. When you will exit the trail at a gravel road, make a hair-pin right turn up onto the gravel road. Later on, turn left at the Academy Trail, under the powerlines. Follow Academy until you arrive at the Equestrian Parking Lot, Aid Station #4.

Continue along the Academy Trail. Turn left at the Horner’s Corner 3-way junction onto the Eagle Bluff Trail, climbing up to a fork in the trail just before a small bridge. Bear left here and continue up to the powerline. Turn right, south, at the powerline and follow it all the way to the end at Eagle Mountain Drive. Note – just after passing a BC Rail bridge, bear left out onto the road to Aid Station #5

From AS#5, turn around and retrace your footsteps all the way back to the Academy Trail. At the Horner’s Corner 3-way junction, turn left, back onto Academy Trail. Carefully cross the park service road and the Buntzen Lake Parkway road. The trail ends at Pumphouse Road, a gravel service road. Turn right and follow it down to Aid Station #6.

From AS#6, turn left into the trail and head up the Diez Vista Trail [affectionately known as FUG, “F-You-George (Gary) Hill” – you will know why as you climb it on tired legs]. As you crest the top of the climb, you will be back at the water station junction, which is no longer in place after your first pass earlier in the day. Turn left and follow this trail [the same one you climbed hours earlier] until you exit at Gate “WP1”. Turn left, carefully cross the Belcarra Regional Park Road, and turn right down the stairs. Once down at Sasamat Lake, turn right at the bridge. DO NOT CROSS THE BRIDGE. Follow the lakeside trail until you reach a set of stairs leading up from the lake. Turn right, up the stairs to the parking lot, then skirt the parking lot and drop back down to the lake to cover the final few hundred meters on in to your finish line on White Pine Beach, in front of the bathrooms.

Congratulations you’ve finished, about 6000 feet up and 6000 feet down over 50km distance.
