The Oak Bay Half-Marathon, Relay, 10k & Kids 1k is one of BC's most scenic running events. Starting at the beautiful Windsor Park in Oak Bay and winding its way through the heart of Oak Bay's shopping district the course then loops out and back along the scenic seaside route of Beach Drive.

As you step onto Orcas Island, take a moment to appreciate its lush beauty. Known as the “gem of the San Juans”, this horseshoe-shaped island offers a perfect blend of arts and culture, pristine lakes, and endless outdoor possibilities. The majority of the island’s 57 square miles are rural and hilly, which makes it a pleasure for drivers and a challenge for cyclists and trailer runners. The curving roads wind through forests, past artists’ studios, fields with old apple barns, and the occasional turn-of-the-century prune-drying barn.
