Now im new all to this so im expecting to be wrong here. Isn't all that sugar unhealthy? Or is it different since youre expecting to burn it off? How does it work?

ok, so I have a question, lets say you're doing threshold intervals, controlling the lactate for perhaps 4mmol, from your experience, how many weeks of doing these threshold sessions before the lactate reading drops and pace needs to be increased to get the same lactate target?

I have a Friend who is into the Hawaii Competitions, and does Competitions that are not even known to anyone. He’s wearing a Rolex. I’m on a Garmin Tactix because I think it’s helpful, but I’m not even running Marathons. So these measurements don’t have much impact on me.

I stress over the stress and see my body battery draining all day before I can exercise in the evening after work. Then I stress I won’t re-charge enough for the next day even with enough sleep. HRV well that just seems to go low and low all the time so I’m starting to ignore it. I wear my watch 24/7 #stress 😂

I’m trying to find a suitable electrolyte drink for my 13yr son. He plays football at a high level and trains 4/5 times plus games. I’m a little concerned with the volume of sugar suggested but I’d be keen to know if you have seen/evaluated this option which only uses real salt, potassium chloride and magnesium glycerinate: ruclips.net/video/eFJzyGbLsMo/видео.htmlsi=aGGGdZrXEmDIsZrB & ruclips.net/video/cHSllLshDUU/видео.htmlsi=tRqbPu3lr70k44Yv You appear to a respected authority within this field so would very much welcome your thoughts. TIA 👍

You call yourself a nutritionst? White sugar…. really?

How are you going to record on Strava without the watch?

I run a half marathon every Saturday. I noted what you said and will use it 👍

When you say 10 grams of carbs per kg of bodyweight, that means for the whole day right? Thanks in advance.

Try being an insomniac and wear a garmin, it great fun. I only use the matrix that I need and laugh at the rest.

I’ve been watching triathlon nutrition videos since 2018. This is hands down the best and most realistic video I’ve seen so far. Thank you!!!

I ran my first timed half marathon about a month back and i was able to take away 20 seconds per kilometer from my original pace and about 15 minutes from finish time. (1:59:00 finish time) I had the problem that i always trained with stopping and eating a banana or something similar and the supply stations except the first one only had water, iso and cola, the last one had some alcohol for some reason. At kilometer 10 i realized that i had to risk the iso drink as i would run out of fuel at kilometer 16 (training experience with longer runs and no supply). Cola was no option due to my low tolerance for high density shugar, it gives me stomack pain in a few minutes and i dont drink cola for about 12 years now so i avoided it. Now that i am training up to a marathon the sodium problem is something i have to figure out too. Thanks for the video and a rough estimate of the sodium intake.

I think it comes down to whether or not you treat health tools as a guide, or a God.

I used to pay no attention to 5 hours sleep a night or alcohol use.. Tracking has shown me how bad my habits were. I now prioritise sleep, stopped drinking regularly and recovered correctly. It's probably added years to my life.

Stupid video

I've stopped using the metrics, but mainly because it throws a wobbler with training load. I swim with form goggles now, so it doesn't pull through swim workouts to garmin. And then they updated the algorithm so my bike computer doesn't add to the load on my watch. So now it thinks my runs are always 'unproductive' because my watch only considers that

I work in counseling psychology and these metrics make me think about psychology tests. We always take the raw data with a grain of salt and it is critical put them into context of the patient's situation and think about the biaises that might have effected the results. Thank you for the video :)

You’re the best 🙏🏼

Those metrics work very well for me. All metrics have errors for all devices but are useful if you know how to interpret them. The video is useless and very very biased.

I like the data as reference, but I just wish Garmin can produce additional devices, so I don't have to wear a ugly watch for 24/7

I love my Garmin, but I’m also realistic about what it does for me. I use a 935 and an HRM Pro chest strap. The amount of data is unreal, and most of it--for me-is unusable in the moment or unusable within 24 hours. HR measures with the chest strap is awesome. My GPS is accurate to within .01 miles consistently and I’ve measured it against a distance measuring wheel. Sleep has been an above average metric. A couple metrics that were valuable many months after the fact were ground contact time and Left-right strike balance since I had broken my ankle and to assess whether or not my biomechanics were different after healing, I could compare old data to new data. The data is pretty unusable in the moment, but great to have for comparison later if you need it. The elevation is complete garbage….rarely accurate. Distance travelled when using the treadmill is always bad. Training status--for me--is absolutely laughable. I can go from unproductive to peaking to detraining in a 4 day time span….I literally use this metric for sheer entertainment value because it means absolutely nothing. VO2 max is also a joke. Though I have never measured it in a lab, my VO2 max from Garmin has jumped 8 points before after one hard steady effort…..and that steady effort was part of a normal training block where I was training 6-7 days per week. Again--I love my Garmin but I know what doesn’t apply to me and my type of endurance training--and that’s ok!

Sorry but this video is all over the place. Firstly you can’t mix validity and reliability. These are two different criteria in science that mean totally different things. You are actually talking mostly about reliability. Then you are talking about is “guesswork”. Garmin actually correlates a whole lot of stuff with their watches. Meaning they have real data to back up their estimation. You can’t really evaluate how good their estimation is. Third is that you are rather describing personal insecurities that you might want to talk about with a psychologist. My take on Garmin devices: They are accurate enough to determine stress and they can aid very well to manage stress and recovery. Take everything with a grain of salt. I even use them with clients in psychotherapy to mange their stress levels. They work fine for that purpose. If you are an aspiring athlete I would advise you to use even more data and try to aggregate it to get a clearer picture. Either use other devices or other apps to analyze your data. Thank you for reading my lengthy thoughts!

I always seem to drop my weight (or at least my fat) when I run consistently 😊 It’s a wonder, then, why I seem to forget about it from time to time. Especially that I love running with all my heart. It keeps me happy and healthy. I’ve been running for 2 weeks now, again, working my way up to a 5k. As a returner my only recommendation would be for those who are in the same shoes as I am, that you start out slow. Do walk runs and then gradually work your way up to a consistent 30min run over the course of 5-6 weeks. It’s rough when your body can’t do what it did X years ago. But it will pick it back up in no time. Happy running everyone! You can do it! 🎉

I get what you're saying. It's just like weighing yourself everyday, can be useful for some people, but lead to eating disorders for others. I'm not emotionally attached to my Garmin data, but do track 24/7. I don't really pay much attention to 'training readiness', or my sleep score, for me HRV, stress and RHR are the most important. Those 3 metrics are what helped discover my thyroid disease, as they got out of control long before I started to have actual symptoms.

any tips for more sleep time (also better sleep)? average sleep is only almost 6 hours or less

I’ve found that since I’ve moved up from less expensive to more expensive and complicated garmin watches, the best guide to my fitness, health and recovery is the rhr number.

For me data points are too general and not reliable for small analysis and the trends provide big picture. However, the training readiness seemed always off.

Nobody said Garmin is perfect, but keeping track of your health and fitness is somewhat important.

After many years of following these metrics didn't lead to better running, I've been moving to training to PRE and paying attention to my HR on runs that week. It's made running more enjoyable.

Anybody who knows anything knows HRV is a completely bogus training metric, whether from Garmin or anyone else. There are simply too many unaccounted-for biological factors that cause HRV to vary.

My Garmin 955 is pretty much accurate for most of the metrics but I agree with you, overtime waking up and anxiously going through my morning report affected me more psychologically than it did physiogically. I've since ditched them for the last couple of weeks and I really feel much better every morning!

I've known for a long time that Garmin metrics are a guess at best, as the scales tell me my BMI is going up and down directly correlated with weight, not muscle. The watch does the same, just best guesses based on inaccurate data. I believe the demonstrated metrics such as actual heart rate, weight, and time, but use everything else as a VERY rough guide.

People forget that garmin is not your coach, its your support device. You can use it to guide you. And its pretty good estimation over longer period of time

Good video and i think you made the right decision for you. I will personally keep it. 1) it helped me so much imoroving my sleep. 2) almost stopped drinking and other unhealthy habits. 3) it helped me feel my body more. It sounds a bit unexpected, but i prefer charts and numbers to understand my feelings 4) i wouldn't be able to do zone 2 running without it and keep it slow enough 5) for me it is really hard to increase volume gradually and things like training load help a lot. 6) i don't really care that much about the metrics that i see. It is logging so i don't have to keep attention to it. If i want to understand some correlation later, i can return back 7) seeing the progress on some metrics is quite encouraging for me 8) when i see it go down, I know i have to make adjustments to lifestyle.

Garmin data is nonsense. I’m 69 and my Garmin recommends me to do sprints at 5.10 miles pace. I could only do 5.30 miles 30 years ago at my peak HR readings are miles out compared to Polar & Apple

Metrics are in line with how i feel for me. So i stick with them.

I generally feel that hrv indicates nicely how I feel, but I dont skip training cause of it

Never slept better after ditching my Garmin watch

THANK YOU SO MUCH!!! This helped me run my first half marathon- just finished and came back to comment:))

Interesting topic. I think in your case you were relying on the garmin info too much to the point you were trying to influence it. For me personally i use it as a gauge, for instance if i ran poorly id look at the data and see if there was something off. Training rediness low or high stress throughout the day etc. I think where i find garmin quite spot on is the peaking training status when it appears. Im always at my best so something must be accurate amongst all the data if it all lines up at a particular point. If say i go on a bender my garmin 265 does seem to pick up that lack of sleep/hangover and takes a few days to return to normal. So seems good there as well.

Same here, the only Garmin metric I pay attention to is sleep. And I don’t use the recommendations, I budget at least 8 hours and like to see the different cycles of sleep the next morning.

I switched to Coros for my current marathon training block because of all of this, I do love Garmin but FOR ME all the data would dictate how I felt for my day too much, morning report, low HRV or Sleep Score, even if I felt good I would think, huh I will have a rough day or run etc...For some the data is probably great but it was influencing me too much.

I don't know if I'm lucky or what but for me, my watch always reflects perfectly on how I feel during the given day. Not sure if it's because I always train with HR strap or if it's because I update my zones in weekly bases (and weight in every morning) but I find it extremely accurate. Hell, even my VO2max is spot on to one that I do in a lab test on treadmill. One thing I do agree with though - Training Readiness can be telling funky stuff if your HRV is off-balance (eg. you were sick and the 7 day average has not stabilized yet)

If your goal is 2hrs. Recommended carb intake is 30g per hour. WHEN do you consume them? Every hour would have you consuming your 2nd gel on thenfinish line?

It only works for 5/10k

For proper documentation of growth even in an unrestricted diet you must still count your calories.

Could I please have your thoughts. If I was a rower and didn't run, I would find this test hard on a treadmill. Would I expect, in using muscles in a way they are not used to, to experience a slower running economy and to show more lactate intervention at a lower heart rate ie lower thresholds than if I did the test on a rowing machine that I am used to performing on? The question is really, is the test sport specific and should it be done on machines or under conditions you are used to?

Great explanation thanks but you need to do a spell check or more like a voice check have a look at where you talk about LT2 and the screen says something like 'producing more lactate than you can clear' which we understand but accidentally you say' more lactate than you can produce'! We know what you mean its all very clear I hope you don't think I am being pedantic, just accurate!

Honestly I love bonk training....it adds MENTAL endurance
