Running for Mysterious PI-pi Ritual, IDM 2025

3/14, 3:14 pm, 3.14 km, then.....mysterious pi-pi ritual

In order to celebrate the international day of mathematics, we will hold a 3.14-kilometer run on 3/14 at 3:14 PM to celebrate International Pi Day, March 14th. The route forms the shape of pi on maps. We invite everyone joining the activity and open their route-tracking app. Let's draw the symbol of pi. Besides that, after the race, we will hold a mysterious pi-pi ritual to bring everyone together in a pi-fect way! Please note that we are not here to compete in a marathon, and we do not have professional road running plans. We have crazy ideas, i.e., to use a mysterious ritual to awaken everyone’s scientific spirit. We hope all participants can run happily and pi-ously complete the ππ ritual! The registration form below is also for recording your name and email.
