第116回・季節の荒川ハーフマラソン 2026

The Seasonal Arakawa Half Marathon takes place in the morning at Horikiri Mizube Park, near Horikiri Shobuen. Participants can choose between a half marathon, 10 km, or 5 km race. The half marathon begins at 10:00, followed by the 10 km and 5 km races at 10:10. This event is designed for runners seeking a timed competition without the higher costs typically associated with larger races. The organizers maintain a low entry fee by omitting certain amenities, such as baggage check and additional portable restrooms. However, they invest in timing services: all participants receive chip timing, with live online results displaying lap times, rankings, and finish times. Finish certificates will be available online post-race. A substantial pacer group is scheduled, offering target speeds from 4:00 to 6:00 per kilometer in 10-second increments, catering to runners aiming for a specific pace or preparing for a longer race. Support will be provided by guests and an MC on race day. Entrants also receive a month of online yoga classes, featuring over 40 lessons for recovery or training.
