Nanaimo Open Water Swim and SwimRun Challenge

Descending from the higher elevations of Vancouver Island toward the coast, the landscape shifts from dense forest to the expansive blue of the Strait of Georgia. As you approach the city of Nanaimo, the geography feels defined by the mountain ranges that press against the shoreline. Westwood Lake, the host venue for the event on August 9, 2026, rests within this transition zone, offering a contained environment for the 1k, 3k, 5k, 10k, and 20k distances. While the nearby Across the Lake Swim Westwood Lake provides a similar setting earlier in the season, this event serves as the primary Canaqua Sports gathering on the island, requiring swimmers to navigate the specific conditions of a freshwater basin embedded in a region shaped by complex geological history.

The local landscape

Swimming here means moving through the traditional territory of the Snuneymuxw First Nation. Beneath the surface, the water's clarity is often a stark contrast to the heavy industry that historically defined this port city. Just a few kilometers from the lake, the earth beneath the university campus hides the Wakesiah coal mine, now repurposed into a geo-exchange system that regulates building temperatures—a unique infrastructure project that leverages the city's mining past to power modern facilities. Looking upward during a recovery stroke, the skyline is dominated by the rounded peak of Mount Benson, a silhouette carved into the terrain by a two-kilometer-thick ice sheet during the last glacial period.

Historical markers in view

While the lake provides the course, the surrounding area carries the weight of 20th-century history. The silhouette of the mountains serves as a reminder of the 1951 PBY Catalina crash, where an aircraft went down into the slopes of Mount Benson, marking the deadliest aviation disaster in British Columbia at the time. The city’s wider waterfront, with its historic Bastion built in 1853, remains a constant anchor for those visiting the area. The basin itself sits near the Buttertubs Marsh, a 100-acre sanctuary that acts as a vital ecological anchor for local bird species within the urban sprawl. Whether you are aiming for the 1k sprint or the 20k endurance challenge, the event integrates these local features into the experience of the race, set against the backdrop of a city that continues to balance its indigenous roots with its industrial legacy.
