No Probs!
The Stanley park seawall typically from May through to late September is often way too busy for anything other than a casual paced ride. Tourists on rented bikes, novice bladers, kids on training wheels, map and camera wielding oblivions just make for too many obstacles.
I avoid it through this period, and favor the roadway instead, and it's a hoot cranking uphill to prospect point then go gonzo down the west slope.
But in the late fall and winter months the seawall is mostly deserted except for the diehards, it's a blast to zoom full speed through the seawall late at night with lights blaring! The only occasional raccoon, skunk or even otter family might get in your way. We might buzz by the raccoons and otters, but we'll give way to the skunks! Only ridden once through a skunk mist! Dang that was nasty!
