TRI Mountain Lake
TRI Mountain Lake is a sprint multisport event held on July 18, 2026 in Liberty Township, New Jersey. The venue is Mountain Lake near 11 Lakeside Dr. East in Warren County. The program includes a triathlon, relay options, an aqua bike event, and a separate 3 mile run that follows the triathlon run course.
The standard sprint triathlon format covers these segments:
- 1/4 mile swim in Mountain Lake
- 15 mile bike course with rolling terrain
- 3 mile run around the lake
Event entry options listed by the organizer include individual sprint triathlon, relay teams of two or three, and an aqua bike category. The separate 3 mile run starts after the triathlon and uses the same run course.
Mountain Lake is described in local materials as a glacial lake about 122 acres in size. It is surrounded by Jenny Jump State Forest and preserved land, and the area includes a glacial peat bog, diverse native plants and trees, and recognized birding habitat. The race is organized with support from DASH Multisport and notes a relationship with the Arc Warren County Chapter as a community partner.
