【7/5(日)・8/2(日)】 三河湖☆サマーRUN（26ｋｍ・13ｋｍ） 2026

The loop around Mikawa Lake is central to this event: a lakeside running course, situated at 500 meters elevation, intended to make a summer long run less demanding than one in town. It has the atmosphere of a modest runner’s gathering rather than a large-scale race, the sort of occasion for consistent mileage and a different environment. You run around the lake with pacers available, catering to those who prefer companionship and rhythm over a solo time trial. Following the run, the nearby rest stops create a "mini run trip" feel, with local Shimoyama foods like goheimochi and eel accessible, offering a good incentive to linger.
