Overview

The 27th Sports Meitran Saiko Marathon 2025, held on Saturday, November 15, 2025, takes place at Saiko Doman Green Park Multipurpose Square, Saitama Prefecture, around the scenic Lake Asahi (also referred to as Lake Sai in some sources,). Organized by Sports Meitran (202 Kanazawa Building, 2-14-15 Shibaura, Minato-ku, Tokyo 108-0023), this non-JAAF-certified race features a flat 5km loop course, described as an “oasis of water and greenery,” ideal for beginners and advanced runners chasing personal bests (PBs). Events include Full Marathon (42.195km), 30km, Half Marathon (21.0975km), 10km, 5km, 20km Relay (2–4 participants), and 5km Parent-Child Marathon, catering to ages 3+ (Parent-Child) to adults. The race offers no time limits for 5km, 10km, and 20km Relay events, with limits of 5:30:00 (Full Marathon), 5:00:00 (30km), and 3:00:00 (Half Marathon). Registration is open from August 11, 2025, to November 13, 2025, via https://sportsmate.net/1-100-27/, with fees ranging from 2,000 yen (Parent-Child) to 12,000 yen (20km Relay, 4 participants), including bibs, timing chips (assumed for timed events), completion certificates (printed on-site), and marathon insurance (2.5M yen death/permanent injury, 1,000 yen/day hospitalization/outpatient up to 10,000 yen). Pair discounts are available for 5km (5,500 yen) and 10km (6,500 yen). Participation prizes (unspecified) and 1st–3rd place awards per event are provided.

Unlike JAAF-certified races, it lacks pacers but offers staff and volunteer support, first aid, and luggage storage (blue tarps or plastic bags). Described on X as “a scenic, flat course perfect for all levels,” it’s a community-driven event with stunning Lake Asahi views.
