Hey All,

I’m curious on your thoughts on determining AeT by using HR from a longer race? In running, AnT/LT2 is often defined as 60-min race pace, is there a race time equivalent for AeT? Obviously, we can’t race a marathon every few weeks to re-establish our zones, but I’m wondering how to use data from a recent race to update thinking about training zones.

All with chest strap:
Current AeT: 155 (treadmill HR drift test)
Marathon HR: 176 avg (191 max) (2:59)
Half-marathon HR: 182 avg (190 max) (1:15)
Max recorded HR: 201

I was thinking of retesting AeT at 160bpm, but given my marathon HR, I’m wondering whether I’ve been significantly underestimating my AeT.

Cheers!

Polsen:

In general I prefer an actual field test like a race for setting zones because it is a true measure of your performance.  Marathon pace will be a bit above AeT typically.  I could see your AeT being in the high 160s-170.  The 1/2 marathon HR is probably close to your AnT given that you ran it in 1:15.  So maybe high 170s-180.  Something that jumps out to me is the disparity between you 1/2 and full marathon times.  That might indicate that you are slowing in the longer race due to local muscular fatigue in the propelling muscles.  The remedy can be doing some muscular endurance work.  For a road runner this can be done using hill work.

 

I hope this helps,

Scott
