98%!

Today I worked out at 98% of my maximum heart rate! I wonder if one can collapse if she pushes to 100%? Did a quick burst on the treadmill - 4km. To calculate one's maximum heart rate, you use this formula:

220 - age

(Ok, so this is a dead giveaway of my age..)

So my max heart rate is 185 (ok go caculate yourself and find out how old I am..)

The maximum I hit was 183bpm today.

So that's actually 98.91% of my max heart rate! My training zone should be about 111 - 157bpm (60-85%) I didn't feel exhausted or anything...but my heart rate dropped pretty fast soon after I stopped running. I hope that means I am fit!
