Achievement Unlocked: Sub-Ten Minute Miles

Another day, another run, another milestone passed. I am currently focusing on improving every aspect of my running. My last run was a great feelgood moment as I learned that my flat course running is a lot faster than I had previously suspected. Today I have broken a speed barrier, pushing through the ten minute mile frontier. This was a conscious effort on my part, not just for the significance of the time itself, but also in an attempt to drive up my heart rate during runs. It is a rather cruel irony that the fitter one becomes and the more fat one burns, the harder it becomes to get even fitter and burn even more fat. Such is the way of things. As one’s metabolism accelerates the body requires more effort to work up a sweat and do serious exercise. Of course, the pay off here is that it also means one is capable of more and more over time. I have observed this over the last fifteen years or so with cycling. I am capable of cycling miles and miles without feeling serious fatigue and my endurance is such that cycling 100 miles is not exactly a huge challenge. When it comes to running I do feel some supplementary benefit as a result of my prowess on two wheels but in this new arena I am largely a beginner.

In making a concerted effort to up my pace and heart rate I learned again that the limits I previously felt by virtue of my body signalling to take it easy were simply illusory. The body is all about economy so far as I can tell, stretching out the calories one has for as great a length of time and effort as possible. I make no claim to expert knowledge here, rather it just seems intuitive that a hunter/gatherer species would be built that way via the marvels of evolution.


Rather irritatingly I can’t download GPX files from Runtastic at the moment so data is all I have today.

  • 5.04 miles
  • 49:49
  • 9.52 minute miles
  • 804 calories
  • 230 feet climbed
  • 130 bpm average heart rate

For what its worth I am surprised at my progress in running. I have never been a strong or fast runner, nor have I particularly enjoyed that much in the past. It has been a pleasant surprise to get this far.
