Event Details
Let's compete with those who have a habit of running and those who want to run with other runners. The Tama Riverbed is a flat course with no gradient difference. The course running on the windy banks and riverbeds is also popular with athletes. We aim to be a tournament where anyone can easily participate and know the region even a little. Immediate issuance of record certificates! It will be an automatic measurement using a measurement chip!
