Keith Jones claims he threw the discus 196 feet which is just shy of 60 meters. If you can throw half the world record you did well! That would be something like 37 metres. Believe me you need to be an athlete to do this. 150 feet is still a long way to throw a 4.4 pounds or 2 kg discus. There are competitions for older athletes in the masters division and when you are over 50 you throw 1.5 kg and then over 60 it is down to 1 kg which is what the women throw at the Olympics. You would think the 1 kg would go really far but that doesn't happen. If you look at the videos of the discus throwers you will see that they all turn in a similar fashion then explode near the end. This looks easy but it is very difficult to master. Some champions have been over 40. Al Oerter for example. If you are of average height you are unlikely to throw more than 55 metres. That is still a long way to throw. When you hold a 2 kg discus it feels big in the hand. So those really tall guys with big hands and long arms have a huge advantage when it comes to throwing. You need a lot of speed then explosive capacity to be a good discus thrower. My best with the 2 kg was 44.16 meters.
