Hi, the rules state:
"The course that the dog endurance trial is to be held on must satisfy the following requirements:
1) at least 2/3 of the course must have a natural surface (grass, field or forest pathways)
2) the course must make it possible to cover the prescribed distance (so that the start and finish are in one place)
Course shape:
a) a circuit, where only overtaking of handlers with dogs occurs, must be at least 20 km in length
b) a straight course, where overtaking and meeting of handlers with dogs occurs, must be at least 20 km in length."
Also: "The maximum distance between checkpoints is 15 km. Drinking water must be available to dogs after a maximum of 15km."
The complete official rules for SVP (endurance trial) are available from me (
