Ultimate Velocity Ratio Harness for sprint training
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!
Cadence or overspeed training must be undertaken with care to ensure that good biomechanics are developed.
