Sunday marks 100 days since the canopy collapsed at the Railway Station in Novi Sad. Five students from the University of Kragujevac will run a relay marathon to Belgrade today to deliver invitations for a protest to their colleagues in Novi Sad, Nis, and Belgrade. The protest will take place on February 15th in Kragujevac, on the Day of Serbian Constitution and Statehood. The relay marathon started at 9 AM in front of the Faculty of Medical Sciences, and the finish line will be in front of the Saint Sava Temple in Belgrade around 10 PM. The students are expected to complete the 115-kilometer route in about 13 hours to deliver symbolic invitations for colleagues to attend the celebration of Serbian constitutionalism and statehood on February 15th.
