I hate pushing myself hard when I run, I don't like the feeling. Most of my training is on a "see how I feel on the night" basis. As a result of this, I hardly ever do fartlek, efforts, speedwork, tempo runs. I do easy pace runs and, if I am feeling really adventurous, I do slighty quicker than easy pace runs. However, on my recent 2 week holiday in Cornwall (during which time a ran at least every other day!!) I was running along the coastal path and a I could see a perfect place to try and find my maximum heart rate. I had done a 20 minimum easy pace run so far (no suprises there!!) and I than went mad and ran as fast and far as I could up a 1:5 hill and then jogged down for 1 minute and then repeated the effort twice more and then took my heart rate. As I still haven't sent my HRM off for a new battery, I to resort to the finger on the pulse method. I literally could not count quick enough. It was way over 220. The generally accepted rough guide of 220 minus my age works it out as 181. Has anyone else found that they deviate from the standard as much as this?
