Choose Trail-Ready Footwear
Running shoes with solid traction reduce slips on mixed terrain, particularly for dusty or rocky sections along the course.

Conquering the Bonelli Park Triathlon: A Practical Guide to San Dimas’ Premier Challenge
The Bonelli Park Triathlon in San Dimas, California, offers a dynamic blend of water, trail, and road that challenges athletes across multiple terrains. Beginning in the cool embrace of Puddingstone Reservoir, the swim segment tests your endurance as water stretches out with a quiet insistence, daring you to maintain rhythm amid gentle waves. After the swim, the course pushes onto rugged trails and paved paths winding through Bonelli Regional Park’s semi-arid landscape, where scrub oaks and chaparral stand firm against the often relentless sun.
This triathlon is not just about speed, but about strategic pacing and embracing the environment’s varied moods. The swim covers approximately 750 meters, followed by a 20-kilometer bike ride with rolling hills that demand controlled power, then wraps with a 5-kilometer run that challenges tired legs on mixed surfaces. The terrain’s intermittent elevation changes—ranging up to 150 feet—keep participants alert, with the hills neither punishing nor negligible.
Preparation goes beyond basic fitness. Hydrating before and during the event is crucial; the dry California climate can drain reserves faster than expected. Footwear with reliable grip is essential, especially for the run where the trail softens underfoot but also can be dusty and uneven. Early morning starts are recommended to avoid midday heat and to catch the park when the light highlights the subtle sweep of hills and shimmering water.
The park's character is fiercely independent—the reservoir seems to push forward, shaping the environment around it, while the trees seem almost watchful, standing guard over the trails. This interaction invites racers to respect its complexity rather than rush through it. Post-race, the park offers spots to cool down and reflect, with picnic areas and shaded benches providing a chance to gauge your own growth against the landscape's steadfast nature.
Whether you’re a triathlon veteran or taking a bold first step, the Bonelli Park Triathlon engages your whole being. It rewards preparation, attention, and respect for the natural elements that enliven this course. Experienced athletes will find tactical challenges in pacing hills and managing heat, while newcomers will appreciate the clear markers and approachable distances that welcome all to test their limits with dignity and excitement.
