(SOUNDBITE) (Russian) WINNER OF HALF-MARATHON, ALEXANDER YUDIN, SAYING:"The track is beautiful. First of all, the sun is shining, the weather conditions are perfect. I have watched some videos on YouTube before coming here which showed how people were pulled out from the middle of the distance track because of the winter storms, extreme temperatures and low visibility. And now you are running with music under the shining sun. The snow cover is perfect. I loved it."
