Enjoyed my 10K run last night at the University of Queensland. I ran strictly to some set Heart Rate numbers for this event. According to the medicos, at my age my max HR should be around 150 but I have previously measured it to be around 160 (at the end of a hard 5K run) and have worked with that number. I am pleased that I was able to finish strongly over the last one Klm and discovered a NEW max HR number of 167!!! So I managed to run the final KLm ( around 6 minutes) at 100% or my previous maxHR, but which now appears to be in reality at around 95% maxHR!!-- this for me is VERY GOOD!!!!
