Ok, thanks for the information!
We rode the trails in Hrastovača, they are great. I connected them to the current Peterova biciklistička staza, since they’re now linked by the tunnel under the railway, start right from there, and are ridden as a single track.
But my question was about the trail even further east, from Radanovačka šuma along Peščarina Street. I added almost all the segments, but for now I left it simply as a nameless MTB trail. I hope someone will give it the correct name someday.

I hvala za trejlove i putokaze, oni su odlični!

Hey, my friend, don’t be upset. Vandalism looks completely different, trust me. I just added the tags following the pattern of several segments that existed before. It looked strange to me too. I’ll remove the names from the segments themselves and leave them only on the main trail, no problem at all.
Also, maybe you can advise? I also added a marked section of an MTB trail a bit further east. The marker color is different there, so I assumed it’s probably a separate trail. But maybe it’s also part of Peter’s Trail?
