Changing Zones

So because I've lost some weight, gotten older, and my resting HR has dropped accordingly, I have just discovered that my HR zones have changed.

Percentile	Old range	New range
60	109	137
70	127	148
80	145	159
90	163	170
100	181	180

This means that I have to re-adjust my runs accordingly. And it also means that my last couple of Tempo runs I have not pushed hard enough as my HR is in my Steady pace range. Time to step it up.
