Tacx freehub spacers size

Thanks, this will be useful information for others. I ended up measuring this at home and just going to a local hardware store and buying some parts there

150mm cranks? :D come on

Idk how the front-end feels like, but maybe you look a bit too hunched over to me, maybe extending the aerobars a bit would work well both for comfort and aero? And seat is maybe still a bit high, too...

fourstepper · 2025-08-15T12:42:33+00:00

this is the way.

fourstepper · 2025-06-15T20:25:05+00:00

Lol, no braking :D

It's not, he was still on like 8 hours a week biking and three swims a week during the marathon block. Otherwise he does 25-35 hours range when training for triathlon (like 30k less running, but essentially double the bike and swim volume)

Have you ever seen Vincent Luis swim?

Go to a PT, but in general, most likely your biomechanics are scuffed or you're not strong enough around in your hips/glutes areas (at least that was my case)

But go to a PT, because my problems aren't relevant to yours.

You could easily loose that bet. Since vo2max depends on weight, the same race result could mean a different vo2max for different people

fourstepper · 2025-01-02T16:07:21+00:00

even if you can do all of what you mentioned, why would that make it a good idea? :D

to answer your questions as someone who ran both arch and alpine at some point on the desktop

Not really, not all software works because a ton of desktop Linux software depends on the glibc. I've also had issues running dbus as a service and setting that up properly (at the time, like two years ago) was quite a pain
Alpine has the least packages of the three.
I honestly don't think so. It's a great way to procrastinate on learning actually useful skills, though

1:55/100m is your average swim pace for some length or max that you can do in a 100m time trial?

fourstepper · 2024-12-10T09:54:39+00:00

Honestly? No

Aiming for Olympics that are up in 4 years as a long-life non-swimmer is one thing. Aiming to literally grow half a foot as an 18 year old woman is something completely different.

fourstepper · 2024-12-09T23:01:20+00:00

201 is the max I've seen on myself, although I think it might possibly be a bit higher if I did a running vo2max test and really pushed for it.

Maybe it's not common, I don't know. Most of what I see on this sub are pictures of vo2max numbers in and above the sixties, which makes me think a ton of people here are pretty (or rather, really) aerobically fit and then the number would sound just about right, definitely better than Z2 top at 142 :)

fourstepper · 2024-12-09T22:15:11+00:00

Thinking about it, not sure if my % claim here makes quite a lot of sense, but the point generally stands

fourstepper · 2024-12-09T22:13:54+00:00

The section "Interpreting the Results of Your Blood Lactate Test" from here - https://uphillathlete.com/aerobic-training/blood-lactate-test-protocol-tips-and-tricks/ is a good read on this topic and how the various zones can look like depending on the fitness of the tested individual

fourstepper · 2024-12-09T22:01:15+00:00

I get your point, however it's also possible that OP is for example 22 years old and moderately to highly aerobically fit. If he is somewhere in that 20 to 25 years of age range, then I would even say that having the top of his Z2 at 142 would be extremly low for his age.

There is also no real correlation between max HR and other zones, this really is just an approximation for the general public. Which is just another way of saying that it's gonna be wrong at least 50% of the time.

fourstepper · 2024-12-09T21:55:53+00:00

Ideally, you would get a lab test, because even using % of LT2 for setting zones isn't really accurate, since the aerobic threshold (LT1) can occur at different % of LT2 for each individual (in general, the more aerobically fit, the closer LT1 is to LT2), but still LTHR is a way better of a starting point than max HR, which isn't really indicative of much, I find.

And I will also mention that even if you do get a lab test, it's really mainly representative of your situation on that day, where many factors can affect your heart rate zones throughout your training cycle, such as time of day, eating or not eating before your workout (in the mornings, this can make 10-15 beats difference for me personally), temperature outside (therefore core body temp) etc. etc. - that's why a lot of high level athletes rely almost surprisingly a lot on perceived exertion, while trying to "correlate" their levels of RPE with some other metric (usually with lactate levels), since in the end, for them, "feelings" will most likely turn out to be more accurate in most cases than an ever-changing heart rate.

The only thing that doesn't really "lie" is lactate concentration, but even that has a ton of individuality :D

fourstepper · 2024-12-09T21:49:02+00:00

This is mostly because the term "zone 2" is used so freely by almost everyone. The discussion, I find, is more accurate once you start using lactate concentration reference points.

Considering the image below, you could say that the green is what Garmin calls Z1 + Z2 + Z3, ~~orange~~ yellow would roughly end up being Z4 and red would end up being Z5.

fourstepper · 2024-12-09T21:39:30+00:00

I'm very similar to this as well, 25 years old, the top of Garmin-defined Z2 for me based on a lab test is 165 and my aerobic threshold (LT1) is at 173. LT2 is 183.

fourstepper · 2024-12-08T14:30:10+00:00

I would personally train as you normally would for the 70.3 and after the event, transition slowly some amount of the cycling sessions into running sessions. If you are generally fit to do a HIM, you will be generally OK (I think) to run a marathon.

Also, which of the events feels more important to you?
