Can I outrun a hornet?

You can outrun a hornet over longer distance, as hornets chase to drive threat away from nest, not to chase indefinitely, and they typically stop chasing after 50 to 100 meters or up to 300 feet when they no longer perceive you as threat to nest, so running away quickly in straight line away from nest is recommended strategy, though hornets can fly faster than humans for short bursts and may keep up initially. Hornets fly at speeds up to 15 to 25 miles per hour for short distances, faster than human running speed of 8 to 15 miles per hour, so they can catch up if you are near nest, but they do not chase for miles, they chase to defend colony, so once you are far enough from nest, they return to nest. If you are chased by hornets, run away quickly, do not swat or flail as this provokes more stings and spreads alarm pheromone that attracts more hornets, cover face and eyes, and seek shelter indoors or in car if possible, as enclosed space provides protection, and do not jump into water as hornets will hover waiting. So you can outrun hornet over distance because they stop chasing, but you cannot outrun them in short sprint near nest as they are faster initially, so best is to run far and seek shelter. If you have been stung, move away quickly as venom contains alarm pheromone that attracts more hornets, and wash sting areas to remove pheromone.
