First off, I wrote an article for Running Times online that is now up on their site. It's called: Avoiding the Hard/Easy Trap. In it I discuss why moderate or easier workouts need to be included in your training plan. So take a look and hopefully it helps you out:
Secondly, Niell Elvin, who is the professor at the City College of NY that provided the excellent 5th avenue mile video I posted earlier, captured some great high speed footage from one of the recent college conference cross country meets. He suggested that we do a little experiment with the video and see how well everyone's assesment of their running form correlates with the runners finishing order.
Niell has posted the top 16 finishers in the girls race randomly on youtube. I'll post these video's below. What you need to do is rank these runners 1-16 in the order you think they finished based solely on their form. Essentially, watch the videos and rank them based on their running form. Post your best guess in the comments section and then I'll post the results once we get a good response.
So, basically you'll post "Runner 5= 6th best form, Runner 9=1st" or whatever you think it is. Also, this video is from 400m from the finish. You can also look at the video from earlier in the race because some of these runners are obviously under some great fatigue at 400m to go and their mechanics are starting to fall apart.
The Video's are in the link below. You'll see that on the right side bar, the video's are listed Runner 1 through Runner 16.
