How the race is run:
Every 800m race has three key parts. Part 1: The start through the first 400m split, with some taking it out fast in hopes of hanging on and others pacing themselves, running fast but efficiently. Part II: The rearranging that typically starts at 400 meters when the runners enter the turn for the final lap, with some trying to maintain and others quickening their turnover, all jostling for set-up positioning along the backstretch. Part III: The final kick in the last 200–150 meters as runners slingshot around the turn and try to find an open lane to the finish. With individual strengths and preferences determining tactics, there’s often more drama and lead changes per second than during any other track and field event.
