DANDO ROUND TRIP40 & 20 is a trail running event held at Asahi Genkimura in Toyota City, Aichi Prefecture, Japan. Taking place in June, it offers runners two mountain course options: 40 km and 20 km. The longer route involves approximately 1,900 m of climbing, and the shorter route includes about 900 m of elevation gain. Both distances require strong trail running ability over flat-road speed.
The 40 km race has an 8-hour time limit, requiring participants to be fit enough to complete it within this period. Runners aged 12 and older may enter, with parental consent needed for those under 18. The venue is located at 68-1 Neyama, Asahi Yahata-cho, placing the event in Toyota City's rural Asahi district.
