Route marking

The route is marked with tape and ground markings. However, we recommend to trailers the use a watch GPS to compensate for any unforeseen events like wild untagging, erased marking, etc.
More on You will also find a suggestion for using a GPS mobile application ("Guru Maps").

Can i run with my dog?
