Anyone with Santa Claus experience knows that ho-ho-ho-ing, handing out presents and prancing around in a fake beard and a puffy red suit can be real hard work. To make sure you're up to the task, check your fitness at this all-red jog event, taking place just a few short days before Christmas. Sign up with a team of no less than four but no more than ten would-be Santas and see if you can run a relay for a full three hours. Family and kids' races will also be taking place, so go ahead and bring the entire gang to Ichinomiya Park on the day – just remember that there's a strict dress code for all participants.
UPDATE: Registration for the Santa Marathon has closed, but you can still check out the action on the day – watching the race is free.
