Translating @Reed’s link into MAPE, since MAPE is a measure of relative error, the chest strap would be close to 0%.

I agree with Reed though I think its important to have a 2 week taper before the objectives if you want to be at full capacity.
ParticipantI had never heard of ear-based HR monitors, so I googled them, pretty cool actually! Searching pub med, I found the following:
This one https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6413847/ found: “The Jabra earbud had a mean absolute percent error (MAPE) of 3.14 ± 6.13%, and a high correlation with the benchmark, r(c) = 0.939, performing well in all three conditions.”
This one https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0238569 found: “Garmin Fenix 5 (MAPE = 13%, LOA = -32 to 162, rC = 0.32), Jabra Elite Sport (MAPE = 23%, LOA = -464 to 503, rC = 0.38”
And here is a systematic review https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7596679/ that concluded: “Although non-optical methods may have the advantage of no light source and reduced power consumption, the performed studies suggested the feasibility of HR/PR measurements only under basic resting conditions in small groups of subjects. Sensitivity to user’s motion may impair performance under exercise conditions, requiring further optimization of the electronics and sensor placements within the earpiece, and noise reduction in the readout circuitry. On the other hand, methods allowing to acquire an ECG, instead of a pulsatile signal, suggested the possibility to trace cardiac activity beyond HR estimation.”
My take away is: theres a lot of variability but it seems like they’re fairly comparable to wrist-based HR monitors. Which is to say, better than nothing but not super reliable.
ParticipantLindsayTroy on March 2, 2021 at 9:25 am · in reply to: Back Pain After Hill Sprints and Mountain Running #51439Hi Beau,
I don’t think its possible to diagnose what happened to your back off the internet, so it may be wise to see a GP and or a PT to get it looked at and to give you some exercises to help strengthen things.
I will say general core strength is good for your back, once you’re able to tolerate it. But you should make sure you’re fully healed before you do anything or else you risk making it worse.
I will also add that at 25 in peak physical health I threw out my back lifting an empty laundry basket off the floor and the doctor said that it was incredibly common for healthy, fit people to injure their backs doing something mild because when you’re doing more intensive things, you properly brace.
ParticipantLindsayTroy on March 1, 2021 at 12:52 pm · in reply to: Total elevation by month in Trainingpeaks? #51415This isn’t quite what you’re asking, but Strava has this feature, and training peaks + Strava talk pretty seamlessly.
ParticipantLindsayTroy on February 22, 2021 at 5:09 pm · in reply to: Regressing in aerobic conditioning? #51122I have to ask… overtraining? what kinds of loads were you hitting?
ParticipantOne other question, have you been tested for celiac disease (true gluten intolerance) or other GI blood loss? I consulted a hospitalist friend who said that Celiac the most common missed cause of iron deficiency anemia. So that would be worth checking out.
ParticipantHave you ever asked your PCP for a referral to a specialist? Without more details, my generic advise would be to look a hematologist or a gastroententerologist to do a work up.
ParticipantIn case you don’t have the books, this is a condensed version of what they say about the Max Strength period:
“Minute for minute, these are among the most important workouts of the year because they give you a boost in strength that pays off in many ways.”
…
“As a quick reminder: This is the stage where we increase the available pool of muscle fibers for the brain to choose from. Increasing Max Strength lays the groundwork for the conversion to Muscular Endurance. Following these prescriptions will produce large gains in strength, with no gains in body weight (often you will lose weight due to the resulting boost to your metabolism).”
Excerpt From: Steve House and Scott Johnston. “Training for the New Alpinism: A Manual for the Climber as Athlete.” Apple Books.
And here is a link where you can find more about the exercises used in the Max Strength workouts: https://uphillathlete.com/general-strength-routine/
I think Rachel is right, in the 8 week plan since there isn’t a lot of time, the goal is to build on what you already have. Whereas in an ideal world, you would first do an 8 week Max Strength period to build up the pool of available muscles
ParticipantLindsayTroy on February 12, 2021 at 10:31 am · in reply to: Calf Pain – Persistent. Solutions? #50768AshRick- I also have this. If I flex my calves I can make them cramp without having exercised in weeks. I’ve found that dry needling is the only thing that releases it but it always comes back.
My PT told me that everyone holds “tension” somewhere, some people its shoulders and back and others its legs (I forget the exact word he used).
ParticipantHi Andrey,
I have some questions for you:
What is your AeT and AnT? Have you done a base Max Strength period? and what is your training history and volume?
You will want to keep your heart rate in Zone 2, and so what this may indicate is that you need more base volume before you are ready to do uphill carries.

ParticipantLindsayTroy on February 11, 2021 at 11:58 am · in reply to: Fitting month-long backpacking trips into the year? #50723Based on the timing it looks like you’ll just have to work around them. The backpacking will count as aerobic volume and will likely comprise all of your volume during these months otherwise you’ll be at risk of overtraining.
If you don’t have ADS, this high volume in zone 1 (I presume based on your description) is what you want. And if you do have ADS, you’ll likely want to spend the time between August and March improving that with Z2 work since I doubt you can adjust the pace of these hikes too too much.
I think it would be ideal to build up so you can tolerate these loads and also do a “gym” workout 1-2 times per week to maintain upper body fitness and they make all sorts of cool travel hangboards and ring set ups that potentially you could cary with you to maintain or improve that fitness. But being aware not to overtrain will be important if you’re doing 6hrs/day of hiking.
With these long alpine climbs, is there an area that you need the most improvement in? If its on the approaches these backpacking trips could be really good, but somehow I doubt thats the case!

ParticipantLindsayTroy on February 10, 2021 at 9:20 pm · in reply to: Fitting month-long backpacking trips into the year? #50701When do these trips occur? a 2 month backpacking trip in January will be different than 2 months right in the middle of summer climbing season.
