A pet dog escaped from her owners and joined a 4x200m relay race at a high school athletics event in Utah – and overtook the winning sprinter on the final stretch. Holly the dog clocked the final 100m in about 10.5 seconds. The crowd roared as Holly overtook the winner just before the finishing line, almost tripping her over. However, race officials did not award the victory to Holly the dog. Video via FloSports and MileSplit | Guardian sport
