Ultimate Velocity Ratio Harness for sprint training

by Neuff
£105.00

The ultimate speed work device! Two waist bands with non-stretch rope and pulley system - safer and more effective than elastics.
The lead runner pulls a trailing runner who has to run twice as fast to keep up as the rope shortens over a pulley on one harness. When the lead runner moves 40m the trail runner has to travel 80m!
