JBMXF大東建託シリーズ第７戦、第８戦 秩父大会 2026

The Chichibu Tournament is a September BMX race weekend held at Takizawa Cycle Park BMX TRACK. It serves as Rounds 7 and 8 of the JBMXF Daito Kentaku Series. The Japan BMX Federation organizes and supervises the event, integrating it into Japan’s national BMX racing structure. The key aspect is the double-round format, where riders compete in two separate series rounds at the same Chichibu venue. The competition takes place on a dedicated BMX track, emphasizing short, intense heats over jumps, turns, and rhythm sections, distinct from distance riding on roads or trails.
