Vermont Sun Run & Triathlon Series
The Vermont Sun Run & Triathlon Series is a seasonal collection of running races and triathlons held around Lake Dunmore, Vermont.

Events for 2026 span spring and summer, including a half marathon weekend in May and triathlon dates in June and August.
Races and triathlons take place at Lake Dunmore and nearby parks. Several triathlon formats offer swim, bike and run segments with an aqua bike option that omits the run. The series also lists course maps, course elevations, race results, and course records for its events.
