Other questions
You will be asked for every team member's name, kana reading, gender, date of birth and running order, so have those details ready before you start. Input screens for athletes you do not have can be passed with the Skip button at the bottom of the page.
Yes, the team representative can submit more than one team entry, but take care not to duplicate the same team. Friend and family entries are not available through the system.
Entry closes at 23:59 on 15 November 2026, and it may close earlier if the field reaches capacity before then.
If the same runner has to cover two or more stages for one team, write this down on paper and hand it to the timing tent staff. That team will be given a reference time only and will not be eligible for prizes. A runner also appearing for a different team is not a problem.
Managers and alternates who run can be swapped using the official order change system linked from the event website, or by speaking to staff at the timing tent on the day. If a manager is registered as a runner from the start, no change is needed.
