Stadion Velenje (also known as Stadion Ob Jezeru) is located on the south shore of Skalsko Jezeru in Velenje, Slovenia. This stadium was built in 1955 and has been renovated several times. In 2010, it was expanded and improvements were done, most likely including a new track surface. Their International Meeting was held here on July 1st, and it was the 19th year of the competition. Meet results are available HERE. It looks like nice facility for track and field. As expected, the field events are all located on the inside. I’m not sure why they have the lone tan patch in the north end though.
Here’s a video from the 2011 meet. The quality is not the greatest, but you can get a pretty good sense of what the track is like:
