We are glad to announce Japan's first disposable Marathon Event bib is available on amazon.co.jp on July 26th, 2018.
Runners need to put bib on chest and run on the race day.
Then result is automatically measured.
Available event is Monthly Kokyo Marathon(Imperial Palace Marathon, Tokyo) and others.
Half Marathon https://www.amazon.co.jp/dp/B07FTRPDVD
This bib has advantage for the following two point.
1. Runners need to return timing chip to organizer after race.
Event organizer need to count returned chip that is time consuming.
And need to pay JPY2,000 when lost to the event equipment rental company.
2. Runners need to go back to finish line even when retired to return chip.
Or need to send it later after come back home.
