The Clear Lake Triathlon in Kelseyville, California, offers an adventure that challenges both body and mind amid one of Northern California’s most dynamic natural settings. Beginning with a swim that feels less like a race and more like a measured negotiation with Clear Lake’s expansive waters, participants are pulled forward by the lake itself, waves pressing as if alive, welcoming and daring at once. The 1,500-meter swim takes place in water ranging between 68 to 72 degrees Fahrenheit in late summer—refreshing but demanding constant focus on pace and breathing.

Once out of the water, the bike leg takes over with 40 kilometers winding through gently rolling terrain. The path skirts along country roads lined by oaks and expansive views of Lake County’s vineyards, with elevation changes peaking around 600 feet. This course pushes riders to find their rhythm between steady climbs and rapid descents, as the sun moves insistently overhead, urging hydration and vigilance.

The final challenge is a 10-kilometer run, tracing a course through Kelseyville’s quiet streets before veering onto dirt trails shaded by trees that have stood longer than most can recall. The ground ranges from compacted dirt to scattered gravel, requiring well-chosen footwear for grip and comfort. Even as fatigue sets in, the forest seems to breathe around runners, leaves whispering encouragement or caution on the wind.

Planning for the Clear Lake Triathlon means embracing the unpredictability of outdoor elements. Daylight hours stretch longer from late spring into early fall, providing extended windows for cooler early morning starts. Proper hydration is non-negotiable; Clear Lake’s dry air fastens itself to skin, pulling moisture relentlessly. Athletes report that layering breathable, moisture-wicking fabrics and sturdy triathlon shoes improve comfort and performance.

Local accommodations in Kelseyville offer practical bases with easy access to the race venue, ensuring meaningful recovery options after crossing the finish line. The town itself serves as a quiet counterpoint to the day’s exertions, with a handful of cafes and markets providing essentials and refueling opportunities.

The Clear Lake Triathlon is not just a race; it’s an encounter with a landscape fiercely itself. It commands respect for its shifting lake currents, rolling hills, and wilderness trails that test endurance and resolve. Whether you’re chasing a personal best or savoring the experience, this event connects you deeply to a region where adventure and environment exist in vivid, practical balance.
