New York, Chicago, Vienna, Singapore and others all already have it, and for the fifth year in a row we will again add Slovenia to the list of runners to the highest skyscraper in the city. The Crystal Palace in Ljubljana's BTC will once again become a unique challenge for one day for everyone who wants to overcome it as quickly as possible. Registrations for the Alive Step Up 5th Run at the Crystal Palace are already open, so you can start preparing yourself or join the teams that are already preparing hard.
