No. Test for your lactic threshold heart rate - LTHR. You can get a reasonable approximation by warming up thoroughly, then switching on your hr monitor and going as hard as you can for 20 minutes. Take the average hr for that 20 minutes.
Then google for either Joe Friel's or Andrew Coggan's hr zones. It doesn't matter which system you use, either will allow you to set appropriate zones for training based on your LTHR.
