For years we've seen athletes getting ever faster but now a study has shown that contrary to what experts had thought - the speeds achieved by racehorses have also been increasing.
Scientists looked at more than 600,000 race times to compare the speeds since the mid 1800s.
Scientists are not sure whether the quickening pace, largely driven by sprinters, is due to breeding, better training, jockey tactics, or a combination of factors.
More recent data from 1997-2012 confirms that the finish line is not in sight yet. Improvements in performance are still on-going, despite heavier handicap weights.
