Saya-pi to Iku! Cross-Country 20k + Big Rope 118 Vol.3 is a small group run held in Kinuta Park, Setagaya, Tokyo. It centers on a spring morning of cross-country running, picnic time, and optional big-rope skipping. The main run covers about 20 to 25 km in loops around the park, typically at a pace of roughly 6 minutes per kilometer. The course may include grassy cross-country sections and road parts, depending on park regulations. The event runs from morning until early afternoon, costs 3,500 yen, and registration is now closed after selling out.
The format is intentionally relaxed. Runners meet, greet, stretch, and begin the long run, with the option to finish early or skip sections to picnic. After running, the group can purchase food from a nearby bakery, greengrocer, or convenience store, located about 800 meters away. The event then aims for 118 jumps with a big rope, though this activity is optional. The organizer, Saya-pi, identifies as Japan's most cheerful support runner. She started with no athletic background, now participates in ultras and trail running, and also organizes "pan-runs," which involve bread.
