ZOZOマリンスタジアムリレーマラソン supported by ぴあ 2026

The ZOZO Marine Stadium Relay Marathon, supported by Pia, is a team running event held at ZOZO Marine Stadium in the Tokyo area in early June. The event features three formats: a 1 km parent-child pair run, a 21 km half marathon relay, and a 42 km full marathon relay. The parent-child run consists of one lap for a child and guardian, with separate categories for preschoolers aged 4 to 6 and elementary school children. The relays involve completing repeated 1 km laps: 21 laps for the half marathon and 42 laps for the full marathon. Teams can be formed as men-only, women-only, mixed, or workplace-based, and family members from the same company division are permitted. Beginners are welcome, and the event is suitable for families, coworkers, clubs, and casual groups looking to share the running distance.
