• Comfortably Numb — Rated an “Epic Ride” by the International Mountain Biking Association, the 23.3-kilometre (14.5-mile) route starts at the Wedgemount Lake parking area north of Whistler and finishes at the Lost Lake Trails; most runners and bikers do it one way and set up a car shuttle. From Wedge, the trail goes uphill, crossing Wedge Creek over the Al Gray Bridge, through old-growth forest, then users pick their way through a boulder field and a downhill switchback section to the finish. “It’s a beautiful forest,” Titus said. “The good thing is there’s not a huge amount of vertical.”

• Singing Pass — The 22-km trail is a Whistler legend. Most explorers start their out-and-back adventure into Garibaldi Provincial Park from the Roundhouse Lodge; note that no dogs are allowed. A few sections — especially over what are known as the Musical Bumps — must be taken slowly.

“When you’re going up the backside of Oboe and Flute, there are some parts that you kind of have to hike, but then there are great sections where you can run again,” Titus said. Be prepared: Check the forecast, tell someone where you’re going and know your route.

Whistler’s biggest annual running event is The North Face Whistler Half Marathon, 10K and 5K ( June 3). The Comfortably Numb Trail Run takes place June 10, followed by Tough Mudder ( June 17-18); the Tenderfoot Boogie Trail Race 50-mile, 50 km, 28 km and 13 km ( June 24); Red Bull 400 (Aug. 5); 5 Peaks Trail Running Series Whistler (Aug. 26); Valley to Peak (Sept. 2); the Whistler Alpine Meadows 55 km, 25 km and 12 km (Sept. 23); and the Whistler 50 Relay and Ultramarathon (Oct. 14).
