Sprints

Sprints are intended to bring ARDF nearer to the public and to attract potential sponsors and new athletes to ARDF.  They should take place in forests or city parks that are easily accessible by the public on either Day 1 or the free day between the main competitions.  Only 80 meters is used for sprints.  The competition course has two loops with a spectator run through the finish area between them. The first sprint loop has five slow-keyed transmitters on one frequency.  The second loop has five fast-keyed transmitters on another frequency.  There is a spectator beacon on a third frequency and a finish beacon on a fourth frequency.  The four frequencies are at least 30 KHz apart.

Each sprint competitor runs through the start corridor, which leads to the area with slow keyed transmitters 1 through 5. After finding all the required transmitters from this loop in any order, he/she runs to the spectator control and then through the spectator corridor to the area with fast keyed transmitters 1F through 5F. After finding all the required transmitters from this second loop in any order, the competitor runs to the finish beacon and through the finishing corridor to the finish line.

A portion of the sprint map from the 2011 Region 1 ARDF Championships in Romania is shown at right with the fox locations added in. The start triangle is at center-right. Competitors found their required of the first five foxes, then navigated to the spector control, marked as a start-finish circle-triangle at center-left. From there they went through a spectator corridor out to find their required of the second five foxes, then on to the finish, marked as concentric circles at upper-left.

Here are additional differences between the sprint and the main 80m event:
