in circles + sidewalk ends, 5k

in circles + sidewalk ends by mthongva at Garmin Connect - Details
this was my first 5k with the garmin 305 using some new heart rate zones calculated using the karvonen method. the weather was absolutely perfect. the pace felt slow but the run was really enjoyable. i noticed that my heart is pumping at 90% even when i'm running at such a slow pace. it's incredible to have that kind of feedback. i know i'm not in running shape, but it makes me wonder about my max heart rate. i think i'll be adding some hard sprints during my runs to make sure it's right. i also noticed how easy it is to become preoccupied with pace and mile splits during the run. so, i'm going to remove them from the display. i'll go with distance and heart rate for now. i figure that the health of my heart and how hard it pumps is my major concern at this point. don't get me wrong, i'm still obsessed with the nerdy aspect of timing and mile splits. they will be great for measuring progress over time.
