I am a risk taker....you?

So where is Fall?! It's nearly 70 degrees outside today!!! I love the heat! Today is a PR (pace run) of four miles total. I increased a mile today. I do a mile warm and cool...these are essential components of the "Spring Theory" training system. The cool down mile is very important because the body is working and recovering at the same time, the warm-up mile used to be non-existent when I was younger but now, it too, is essential. I call it making the flip. So the idea is to run MP for consecutive miles, increasing each week. The problem I am having is running too fast! Today I had an 8:21, 8:33, these are faster than my MP goal which is 9's. For some reason my body likes this 8:30ish pace but it is not sustainable.
  I noted some residual soreness from my "40 min of Hill" and I suspect the hills are making me stronger thus the 8:30 pace...
   The key is not to get injured as I try to ramp up miles. It will be a slight risk and goes against traditional training methods, however, because of muscle memory, years of running, I think a person can ramp up over and above the 10% per week. Not much, mind you, but stretching it.....taking a risk as I press the spring!
  Tomorrow I will do a "Roborun" or treadmill, why? Less impact, greater control over conditions, and it's part of the over all plan. It sure felt good to run today....I count it a blessing, isn't each day a wonderful gift!! Hope you are well and running! Peace!
