HR Training Zones:Need Confirmation

Nate Parady

Zone 1
65-78%
Zone 2
78-89%
Zone 3
89-93%
Zone 4
93-99%
Zone 5
100-102%

 Just want to make sure I'm following the right zones.  Above is what is listed in the Quick reference guide in the wicki. Below is what is listed in the Data tool for me.  I am a Heart Rate Athlete.  There is a pretty big difference in the two.  Especially in the zone 1-2 range.  I'm only now really looking at this as my OS has ended and I'm trying to get a better sense of zone 1 and 2 for my transition period.  Spent the last 5 months in zones 3-5. 

My big question is: Is my zone 2 up to 75% or 89%...my gut tells me its up to 75%. or should I say my legs tell me that. 

Looking for some confirmation.  Thanks Team.

Z1 / < 70%:	< 139
Z2 / 70-75%:	140-148
Z3 / 80-85%:	149-157
Z4 / 95-100%:	158-163
Z5 / > 110%:

I would follow the data tool...but clarification and confirmation would be good!

The % numbers in the data tool are for power users. The Z1, Z2 are referring to the HR zones and are based on the percentages you see in the wiki. So although in the data tool you see the Z1/>70% next to your 139, it's not actually 70% of your HR, its approximately calculated based on the HR chart from the wiki (I believe it takes a few other things into account which is why it isn't perfect). So ignore the percentages in the data tool, that's for power only.

See P's post in the trial forum where he talks about it: http://members.endurancenation.us/Community/Forums/tabid/101/aft/3442/Default.aspx#71359

@Jennifer, thanks for the link and info...so my zone 2 goes all the way up to 89% of my average HR for a 40minute TT...This changes everything.

Nate, yes, go by the numbers in the data tool. Don't go calculating it yourself, because there are some other considerations if your HR is very high or very low.
