Hey All,

Starting the 24 week Mountaineer program and just would like a sanity check on my AeT numbers. Have done the test 3 times, twice with a couple of redbulls in my system, and once without. The one time without my HR was around 155 then rose to low 160’s in the last half hour. The two times with caffeine my HR pretty much immediately pinned to 163 during warm ups and stayed there the whole time with very little variation (spiked to 167 a few times but I think that was more dependent on what song I had playing.)

My initial thought would be to just call it 163 and train there for a few weeks but such little variation % wise makes me slightly weary of this. I did try to start at 170’s a different time but 30 mins in I was up to 184 and struggling to nose breath/converse with myself so I called it off.

Based off the age formula I should be around ~156 if thats any help.

Thanks! David

You’ve just shown that the advertising slogan “Red Bull Gives Wings” is true.  The sugar boosted the glycolytic (carbs) contribution to the energy needed for these test.  The caffeine jacked your HR.  As test you can put on your HR chest strap and drink a Red Bull.  You will see your resting HR 5-10bpm higher if not more.  Rising from 155 to low 160s over the test (3-4%) indicates that you were very close to your aerobic threshold when you started at 155.  My recommendation would be to use that for the upper end of Z2 and retest, without the Red Bull,  in a 4-6 weeks.

I hope this helps,
Scott
