Not a bad result, ran on the outside pretty much the whole race and he looked like he didn't know what to do most of time. He is clearly not a miler, he looked liked a 4/8 guy doing a mile training run. I suspect he could have run a second or 2 faster in a different race and most importantly he did what he had to do to win. (You can never knock an athlete doing an event they don't normally do and they win the race.) I use to train with a group of pro 800m runners and we had one guy who was a 46x/1:45x 800m runner and he would take a walk break on a 5 mile 7mpm training run...some people are built for speed.
Btw, If I was Jock and/or his coach, I would not change anything about the way he run his 800s, becasue the 800 is a very difficult race to run in a pack; your chances are better running from the front or the back. Letsrun is mostly LDR types and always comment about 800m athletes who lay off the pace or go out too fast, guys who are 800m runners know that there is a very ligetimate reasons for doing this. In the years to come, Jock will get stronger and be able to go out in 50 point and come back in 52, which is a better appraoch than trying to go out in 52.
When you are averaging 52 seconds in an 800m, you are basically sprinting, which means your body is in the air more than in contact with ground. Getting bumped, boxed in, having to chop your stride, being in the wrong position are things that by the time you recover from, the race is over. There was a proposal back in the mid-80s to run the frist lap in lanes. You hear elite athletes all the time say they caught in the wrong position. It is a fact that every athlete that makes it to a WC or Olympic 800m final has a shot at a medal...it's really not about who is the best, its who can execute the perfect race on that day. Obviously if you are a David Ruhdisha, you can make some small mistakes. All of the sub-1:42 races were choreographed to get a fast time, Coe, Cruz, Ruhdisha and Kepititer ran right behind the rabbits, got out in 49/50 and had a clear path to the finish line.
