A Triathlon is a sport that has 3 things, bike, swim and run. You have to swim and then pick a bike and hop on it and go around the flags. When you pass the line you have to run past the flags and to the finish line. The rule is to not ride your bike when you pass the line, if you pass the line riding your bike you were get a 10 second penalty. Don’t ride your bike in the transition area.
