If you are in Kiev for a long stay, all the sightseeing running has already been made and you need a proper place to actually train, go to the beloved stadium with soft pavement on the very center of Kiev. Any time of the year, professional athletes and amateurs prepare for races and train there. Atlet is a Soviet-time stadium that has been reconstructed to meet the needs and requirements of our changing world. It is part of the Olympiisky National Sports complex, which has all the facilities used by the national teams for different kinds of sports.
Kiev now has a lot of running and triathlon clubs that also train here, so you can look and choose one for yourself.
The stadium has a shower and changing room facilities, but those are only available if you are a part of any club that has an arrangement with ATLET. Try it!
