How to find out the running power zones?

Just sick of having all my running showing all wrong (always at the Z5) so was wondering if anyone knows how do I set up proper running power zones at the FR955? I have no clue and thought that the watch was, with time, adjust. I won't be training by it, but it would be nice to have it somewhat accurate so, with time, I can have a benchmark to compare against...

TIA

If your forerunner 955 detect your lactate threshold, it sets new heart rate zone and power zone. But current official firmware version has some trouble when it comes to detecting LT. Fortunately, Garmin fixed this bug in beta firmware 15.09.

So did you do the LTHR guided test and it also updated your power value?
