“It was a truly family-friendly race, full of the city's warmth.”

The runner took part in the half marathon as a guest runner in 2022. The runner experienced headwinds along the coast, the course through rice fields and residential areas, and plenty of support. The runner appreciated receiving local specialties and handmade bread.

READY TO RUN

From race morning to after the finish.

Your start time, fuel and bag drop.
Know them ahead and the run feels easier.

The Komatsushima 'Headwind' half marathon is popular due to its special appeal of running through Japan Self-Defense Force grounds,

so registration closes quickly.

The 2026 race was open for online registration through RUNNET from July 1 to September 11 at 11:59 PM,

but the half marathon and 10km categories reached capacity midway through the registration period and closed early.

The venue is located in JA Aisai Ryokuchi in Wadajima-cho, Komatsushima, Tokushima Prefecture.

Half marathon and 10km categories start at 10:00 AM, while the approximately 2km Enjoy Run (run & walk stamp rally) category starts at 10:10 AM.

Details about capacity or time limit are not posted separately on the official homepage,

so if you aim for the next race, it's safest to apply as soon as registration opens.

Times are local to Komatsushima. Check the latest official information before the race.
