Cal Tri Walnut Creek 2025 returns on August 17, 2025, at the beautiful yet demanding Walnut Creek Park, just 13 miles from Charlottesville, Virginia. Regarded as one of the toughest in the Cal Tri Events series, the venue hosts 18 distinct formats, including Olympic and Sprint-distance triathlons, duathlons, aquabike, aquathlon, swim-only, and run-only (5K & 10K) races. The Olympic triathlon challenges participants with a 1,500-yard swim, 24-mile hilly bike ride (~2,000 ft elevation gain), and a 10K trail run with ~520 ft ascent, while the Sprint triathlon offers a 750 m swim, 11.4-mile bike, and 3.1-mile run. Youth Sprint events are free for athletes aged 7–17 and follow similar formats. Due to warm (~85°F) lake temperatures, wetsuits are prohibited. With chip timing, well-supported aid stations, and a lively post-race atmosphere including food and community vibes, Cal Tri Walnut Creek is a highlight for endurance athletes seeking a serious test.
