The Stanley Park Seawall is a 10-kilometer loop. The eastern half (Coal Harbour to Brockton Point to Prospect Point) hugs the cedars and is shaded almost the whole way. The western half (Prospect Point through Third Beach to English Bay) is exposed to afternoon sun on cliffs facing southwest and there is nowhere to hide.
These three are picked for the cool half, started early. If you’re running the full loop, Stay Cool now routes you counter-clockwise from Lost Lagoon between 10 AM and 3 PM in summer — the geometry just works better.
