I believe Hart's method is excellent! You can't argue against the results. I do know that at La Crosse, they routinely (when Guthrie was there) took quarter-milers who were 50 point at best out of HS and took them down to 47/48 second quarter-milers and in a few cases 46 or better. I never saw a frosh come in when I was there who didn't improve. Most of the guys recruited to run 4's there improved, walkons however would improve, but not significantly. I use the model program that Bayler, LaX have used, however I have made small changes to it and I have added speed to it as well. Strength will take you so far (as far as race strength), but there will come a time when Wariner who is unbelieveable will have an issue with an athlete who doubles in the 2/4, but has a 200m time that is much faster than his. What made MJ unbeatable in the 400m was because he could go through 200m so much faster than anyone else. When you can run 20 point for your first 200m of the 400m, there aren't many quarter guys who can do that. So I look forward to seeing Xman mature. There could be a great rivalry there for the 08 trials.
