The Sled Dawg allows the athlete to run with additional, consistent resistance without interfering with running form. Moderate levels of resistance during sprint training helps increase stride length, a key component of speed. The steel sled carries 200+lbs. The athlete is connected to the sled with a 10' strap connected to a shoulder harness. Athlete activated quick release feature also available allows the athlete to detach from the sled and strap at any time.
