About the Event

2026 Cal Tri DC - 6.14.26 in Marbury, Maryland, United States on June 14, 2026. This event combines a trip to the nation's capitol with a race venue just 30 miles south of Washington DC in Maryland's General Smallwood State Park. The course will take you through diverse landscapes and community energy that captures the essence of this region on an early summer day.
Race day, June 14th, finds Marbury bathed in golden sunlight as temperatures hover around 29 degrees Celsius with a comfortable average humidity level of 68.3%. A gentle breeze from the northeast will keep things fresh and not too oppressive for your run along the park's trails. The community spirit is palpable, with participants and spectators coming together to support the event.
The history behind this race dates back several years, evolving into a beloved tradition that brings together runners of all ages and abilities. This year, 18 exciting events are offered across three distances—Olympic, Sprint, and Youth Sprint. From the swim and bike segments to the run portions, each distance offers unique challenges and opportunities for personal growth.
The course begins at Sweden Point Marina with a hard and dry surface that provides excellent traction during your runs. You'll navigate through varied terrain including forested paths and open fields as you complete the five-kilometer race or the longer Olympic distances. Aid stations are strategically placed to keep you fueled throughout, ensuring no runner goes without support.
Weather-wise, prepare for temperatures in the mid-20s with a chance of light rain given the average rainfall is 3.4mm on June days. Pack layers and consider wearing moisture-wicking gear to stay comfortable during your race. For those choosing the swim events, water temperature averages at 82 degrees Fahrenheit; wetsuits are allowed but not necessary.
