The Ehime Marathon is a popular road-running event held in Matsuyama, the capital of Ehime Prefecture on Japan's Shikoku Island. Starting in front of the historic Ehime Prefectural Government Office, the course runs through the city's neighborhoods and scenic northern outskirts before returning to Shiroyama Park, beneath Matsuyama Castle. The race is known for enthusiastic community support, well-organized race services and warm Japanese hospitality. Its varied course combines relatively flat sections with gentle climbs, offering runners an enjoyable challenge. Certified by World Athletics/AIMS, the marathon attracts more than ten thousand participants and provides an opportunity to discover Matsuyama's cultural landmarks, including the famous Dōgo Onsen hot springs.
