I will be 56 in a couple of months so I guess that means I am an older newbie. Anyway, I used to be very active until about 12 years ago, running, squash and a myriad of other stuff, then it all came to a grinding halt. The arrival of twins. Now these guys are at an age when I need a lot more of everything to try an just keep up with them, failing frequently I might add. I started running on a regular basis last September, 09, and have manged to maintain 4 to 5 runs a week. The route I run is 5.6 Kms and I so far I have managed a best time of 28:51 with an average time of around 30 mins. What I am interested in is my heart rate. It max's aound the 170 mark with an average in the 150's. I am new to heart rate monitors and I am wondering is this ok for someone in my age group.
