New Coros blog post re: Jakob's training

Interesting to compare this to Arturo Barrios workout from the late 1980s at altitude in Boulder, Colorado. His 20x 400m in 61 w/ 200 jog was 5 fewer reps and several seconds more recovery, but it was at altitude, so maybe actually a slightly tougher workout? What do you think? Of course, he was racing 10ks, not 1500s...

Stupid Coros is the brand name, not the model name, and the problems I listed I believe are endemic to all its models including Stupid Coros Pace 2 and Stupid Coros Apex 2 that I’ve owned.

Is this really that hard of a workout? Like doing 6 x mile at 10K pace doesn’t seem crazy and that’s way harder than breaking it up into 400’s

I also had Pace2 and now Apex2 and can confirm that charging is a chore, quite often you would plug it in and it doesn’t charge. With Apex it started less than a month after getting it! At least while the watch is new you don’t have to charge it too often.

But I love my Coros! I got pace 2 because it was a very cheap and very light watch that did everything that I wanted, and fell in love with stuff like nylon strap, alarm, timers, widget with time till sunrise/sunset. Probably available on many if not all other watches today but my Garmin 235 had none of that and now I can’t be bothered to switch brands. Also I think they were the first to introduce track mode for correct distance/pace on track.

He's European..under 8 mins a mile for a CD for a pro isn't setting the world on fire

I like your positive outlook but I'll be very wary for Jakob. For one, threshold fatigue is nothing like 54-55 second 1500m/mile running although it presumes to set you up to hold the latter pace better!!! Jakob has always been a 5k/10k guy, but for the lack of an Achilles tendon in 2024, I assure you that the moment he starts going 55 second pace he will know it's different and more lethargic and strenuous than it used to be!! It has to be because Achilles tendon scar tissue works like that!!!

Even for slower runners it could be doable. 5k - 22:14
5k-7:09 and 10k-7:27 paces (split the difference and run 7:18 pace)

400m rep equivs using 7CV (7:17-7:27 range) on Tinman - 1:48-1:51 per lap

Sounds like a tough but doable one even with 45s rest.

I saw in the graph it looked like he took a longer break at just about halfway (13 reps), I’m wondering if this was to give himself some time to get some lactate readings? It’s the only thing I can come up with so anyone’s guess is as good as mine

"I am definitely starting to reach a point in my career where I need to work on all the small things...I am at such a high level that minor changes for the better, can mean big improvements. With the data I am collecting, I believe I can have some marginal gains, which is exactly what I need for the future."

So in other words these watches from Coros/Garmin etc only serve as small minor benefits and none of us are even close to Jacobs fitness so none of us need those marginal gains.

Sorry to inform all of you folks on LRC, but the moment a high performing athletes purchases, wears and irradiates himself with digital electronic wireless device like COROS, it's game over for their high performance career, so over!!!!! I give you 2 examples of persons whose careers became SUDDENLY BLIGHTED with mystery injuries and/or reduce high-performance ability-----get slower and worse as an elite athlete:

1) Kilian Jornet. Once he attached that COROS to his body like glue, game over, he was injured again, and again and again. His running got slower, worser, more mundane.

2) Emelie Forsberg. Wife of Kilian, once she also got COROS she also hit the bottomless pit and was never worst in terms of speed, endurance, speed endurance and aerobic resistance/threshold.

3) Desi Linden. When she won Boston in 2018, she sure didn't wear COROS but when she used and wore one, she also retreated into ignominy, bye-bye for her!!!! Look where she is now, running like crap and all these has nothing to do with age, while of course the increase in anthropogenic RFs also factor into her decline obviously, not to mention!

4) There are so many, so many, so many more top tier elite athletes who got in over their heads when they became big names with big sponsors and started using and wearing digital electronics on their bodies AS IF THEY ARE SOME BIG-SHOT CELEBRITY that THEY DIDN'T USED TO during their rise to the top of the podium ladder and almost immediately their career took a turn downhill with first signs of poor (slow) performances, then followed by losses (where they used to be number 1 they were now number 3, 4, 5, then followed by injuries (where they used to be so bloody durable day and night) they now easily got injured merely side-stepping their playful dog ala calf strain or heel pain or whatever the heck!!!!!!!

Dear LRC, just to remind you folks, THESE ARE THE SEEMINGLY UNEXPLAINED MYSTERIES OF elite high-performing athletes whose fortunes reversed JUST AS QUICKLY AND INSTANTANEOUSLY as their subscription with digital wearables, mobile phone upgrade plans, home WiFi broadband upgrade or whatever latent technological seduction!!!! Whereas they deserted the agrarian herdsmen life of frugality and subsistence farming devoid of technology hence EMFs that precisely made them what they became in the first place!!!!

What irony, I lament and I depress over!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Jakob is not as educated in the region of anthropogenic EMFs as I Khamis am, so I do empathize with him whenever he THINKS that he needs these technological aids to make tiny inroads into big improvements because the laws of Physics says that these technological aids are 'BORROWED SPACE AND TIME'------meaning it must be RETURNED-----MEANING JAKOB MUST SURELY PAY WITH HIS HEALTH HENCE LIFE!!!!!!!

There is reaping/paying for every sowing-----this is METAPHYSICS/PHYSICS, can't run away from it.

No no no no, you are greatly mistaken, digital wearables consume and devour your health, your physiology, your immunity, it's bad for you in other words!!!! There is no 'small minor benefits' without 'bigger major harm' to your biology!!!! You think Hicham EL G and Haile Geb wore COROS in the 1990s????

Come on dude, pls pls THINKKKKKK!!!!!! EL G and Haile Geb were far greater and more powerful and effective distance runners than Jakob can ever dream of and underpinned by far lousier shoes and track surfaces to boot!!! The hand-eye and arm-leg coordination and synchronicity in El G and Haile Geb is at least 1000 times better than Jakob's!!!! They move more fluidly and beautifully than Jakob. Their athletic bodies were more SUPERCONDUCTING than Jakob's!!!

It is sort of hard when you did 90 mins of running including 30 or so around MP in the morning.

and it is really right between 5k/10k not 10k pace. We are talking paces where a couple seconds make a huge difference in difficulty. It isn’t like crazy hard like when you see 4x1 mile at 5k pace but I can totally see how the last half dozen are doable but tough.

You good bro?

Jakob has different genetics than those guys and he also isn't doped to the gills like them. Of course he isn't as smooth as them but when it's all said and done he'll be better than them because of his years of building the greatest engine possible.

Jacob can run 5000M in 12;30

so 62 is 2 seconds slower per 400m than 5000m pace

so for mortals that run 15 minutes for 5 K, that is like 70 seconds per lap plus 2.

72 seconds per lap.

very doable when you are in shape

What sort of question is that 'you good bro?'???

Of course I'm better than the Sun duh!!!!

Jakob has different genetics what???? Seriously??? Did you read the SI article by UK journalist in 1999??? EL G was a descendent of the long-legged bird-framed Roman Italian herdsmen tribe with long limbs and superior genes!!!! Built like a land bird is what he meant!!!!! Hence aerodynamic as well.

And what about Jakob??? His bone structure is so obtuse and non-aerodynamic, the way his arms relate to his legs is also soooooooooo resistive and impeding unlike the SUPERCONDUCTING EL G!!!!!!!!! El G's stride length is also longer than Jakob's due to his bird-like sleek frame!!!!!

What genetic superiority are you talking about Jakob over El G huh??????

What greatest engine possible when the comparison is void whenever the elastic shoe quality of Jakob's is too much superior to El G's dumb ones????

The only saving grace for Jakob is his breaking the 3:26:00 WR which ONLY REDUCES the gap between him and EL G----meaning he is still worse athletically than EL G because he still broke the WR with superior shoes and track surfaces.

You need to have a sense of weight and scale you know???

😂😂😂😂😂😂😂

Am I living free rent. You are going insane. Jakob doesn't have to look and fluidly and beautifully as them because he isn't them! Chill out

Jakob can run what??? 12:30??? Come on man, LOL, Haile Geb, Kenenisa Bekele, Hicham EL G, Daniel Komen can all run 12:28 given the same set of Nike Vaporfly spike shoes and bouncy springy polyurethane foam constituted track surfaces!!!!!!!!!!!!!!!!!!!!!!!!!

You sure or not dude???? The only thing that doesn't favor me is that Hicham EL G is obviously retired and not here to render the comparison alive for me!!!!!! But objective evidence of EL G running a 12:28 with all the same luxuries isn't needed to prove my claim right, because only deductive and inductive rules of reasoning THAT BYPASS OBJECTIVE EVIDENCE/FACTS are needed to equally (as good as) prove and qualify my claim right!!!!!!!

Jakob is good and all, I know that!!!!! But I need to see you pay homage in your sentences in this manner:

"Jakob can run 12:30, but heck El G could have run 12:20 with the same aids".

Thank you!

"Jakob can run 12:15 doped, but heck El G could have run 12:20 with new shoes and his trusty PEDs."

Obviously this is insane Jakob has run faster over 5000m and may in the future over 1500m, but El G was so doped. Which is a much better help than the shoes. Seriously its plain logic. All of El G's training partners where popped.
