100 km Triathlon
Swim (2km) - to be released
The Swim
The Vancouver T100 100km Triathlon kicks off with a thrilling two-lap swim in the refreshing waters of the Pacific Ocean.
Athletes will experience the excitement of an Aussie exit, emerging from the water after their first lap to a surge of crowd energy before diving back in to conquer their second lap.Â
Bike (80km)
The Bike
New for 2025 will be a 80km bike route that takes in America’s first National Recreation Area at Lake Mead, a year-round national park offering a unique blend of natural beauty and historical significance. Amateurs doing the 100km triathlon (2km swim, 80km bike, 18km run) will do a single loop, out and back course, that will include a special tour of mountains, canyons and valleys around Lake Mead – the US’s largest reservoir, which was formed by the Hoover Dam on the Colorado River.
Run (18km)
The Run
The Lake Las Vegas T100 run course features three scenic 6km laps around the lush grounds of Reflection Bay Golf Club. Each lap winds along smooth cart paths with gentle climbs, fast stretches, and stunning views of the lake and desert mountains.
Athletes will soak in the quiet beauty of the course while staying focused through subtle elevation shifts. The race finishes in dramatic fashion on the 18th hole, right by the water’s edge—a perfect end to a challenging and inspiring run.
