Hi guys,

I did both the AeT test and the LT test this past week. AeT went well and was determined to be 157. LT test absolutely destroyed me and I was very sore and feverish with an elevated heart rate for 48 hours after. I suspect that I ran the LT in Z4, but I was able to sustain the LT pace and HR for 30min, so I’m a little bit confused how that’s possible. I would have suspected if it was a Z4 effort, I would have blown up before 30min but that wasn’t the case. My LT was determined to be 172, but I suspect it has to be closer to 167 if I hope to recover quicker from Z3 work in the future. Just wondering if you can shed some light on why the LT test had such a stressful impact on my body when I was able to maintain the pace for 30min? For context, not sure if it makes a difference but I did this LT test outside this year, whereas I did the LT test on the treadmill last year and did not have the same issue of my body shutting down after.

Thanks,
Chad

…feverish with an elevated heart rate for 48 hours after.

To me, that sounds like illness rather than post-test fatigue. I would keep your training easy for several days to see if any other symptoms develop.

I would have suspected if it was a Z4 effort, I would have blown up before 30min but that wasn’t the case.

30′ in Z4 sounds about right. Z3 ranges from 1-2h.

My LT was determined to be 172, but I suspect it has to be closer to 167 if I hope to recover quicker from Z3 work in the future.

Five beats is splitting hairs. Heart rate is never that precise. Use 170 as your AnT HR.
