Of all of the events in track, the 800 would probably be the most dificult with no training. Even if you have tremendous talent, you don't understand the concept of pushing through pain and how to get your body to keep moving when it wants to stop...that is not a natural thing, it's learned. Over the years, I have had some kids who ran what I thought was amazing times off no running specific training, but no where near a 1:50 800. I had a 15 year old run a 2:02 800 after the first week of practice, which he probably could have run with no practice. He ran split 1:53 at in late April and 1:54 open at the state meet. He ran 1:51 the following season, with no work over the summer, no XC, no indoor and only practicing 2-3 days a week in the spring. But, this kid was a soccer prodigy, he played soccer almost 7 days a week and did a ton a conditioning drills with a private coach. He was being looked by pro teams in high school and occassionally ran road races with his mother and father who were runners. I thought that was pretty amazing, but that is not even close to 1:50 with no training as the caption states. Btw, this kid did not run his senior year and was playing MLS at age 18.
