About this event

The "17th Arakawa Half Marathon & 30km" incorporates organizational efforts to make it easy for runners to participate, including low entry fees, industry-leading timing technology, abundant pace runners, and cheers from the MC and special guests. Runners competing in a race for the first time or those preparing for a full marathon can fully enjoy the unique race atmosphere that cannot be experienced during regular training. While offering excellent cost performance, the event supports runners through a real-time results website service and encouragement from guests. Pace runners are scheduled to be deployed in 10-second increments from a 4-minute-per-kilometer pace to a 6-minute-per-kilometer pace. As a participant perk, one month of online yoga will be gifted. The half marathon starts at 10:00, while the 10km run and 5km run start at 10:10.
