Thanks everyone for the well wishes - as annoyed as I am that this happened, like I said it could've (and has been) worse, and I've had a decent season with a win under my belt. I'll be back!!

ER doc said 6-8 weeks, we'll see how long it really takes. Not gonna rush it considering the season is so long here.

Dammit don't make me laugh!! lol tho

Climbed and descended a 10,000 ft volcano this morning. The descent took longer than any other climb I've done except Hamilton.

Are you in Maui?

Some need more data than others.

Did you sacrifice a virgin?

I don't think SpO2 use at effort level where it starts to decline needs to be weird or beyond any amateur that uses a HRM or Power Meter. <$100.

Measuring SpO2 is cheap.
Repeating: A rider doing an interval does not really know when they are starving the cells of O2 (not getting into lactic acid measurements). I noticed SpO2 does not drop linearly. In Zone 1,2,3 its still around 98+. In Zone 4,5 it moves and not 1:1 with HR, more closely related to burn in the legs. It feels like a better measurement for know AT than HR. If I knew my son could hold SpO2 92 for 30 min - I'd have him use that over HR using your ear lobe design device.

For training - if you are not 88% you are not Zone 5 (I made that up) but the application is there.


I doubt more than doing squats turns you into a frog.

5, VO2 20 - but due to growing up, altitude tents, diet, riding or mom's genes (who won Caspers SR by 45 min). There were junior State TT champs that were using Hypoxia when my kid was 10 and by 18 those kids were not winning anymore.

It should be obvious its about me. He was steered in that direction. I also steered him to doing his homework. However there are no whippings and he gave up soft drinks on his own.

It should still be 20.9, your tent may be leaking, or the calibration is a little off.

You should read up on carbon monoxide rebreathing techniques for determination of total hemoglobin mass. Total body hemoglobin mass is a far better predictor of performance than the concentration in a blood grab sample that changes with hydration etc.

It makes sense that SPO2 would remain normal in zones 1-3, it's not going to drop off until you start to get to some kind of extreme. It also makes sense that it would be a better measure of high-end aerobic effort than HR. What you really want to know re: what the heart is doing is cardiac output, which is HR x stroke volume (ie the amt of blood you push forward with each heartbeat). You never know stroke volume and that's influenced by hydration status and degree of vasodilation and probably a number of other factors.

The greyhound comment was meant to be a joke, basically greyhounds are physiologically different than other dogs which is why they are fast. So all you need to do is figure out how to induce the same physiologic changes in a cyclist and they will be fast too. Maybe not have enough endurance, but faster than they were.

I was like 99% sure this was the case.

Anyway, I bet he sneaks pocket bacon on his rides, and has a girl at the end of each out and back.

Doge

Yes I know - 20.9 its the same wherever you go - except LA in the 70s - Dalton or some dead guys law. It is not the same in the "tent".

I can't figure out if you are serious or not, but those are good links.

rideaz

I know everyone is different, but I had 2 broken ribs (displaced fractures) and took 3-4 weeks off the bike. I was able to do some hiking after a couple of weeks. I waited a bit longer before I went back to group rides, just to reduce the risk of crashing on them. Mine hurt like heck for about 10 days or so then suddenly one day felt better.

So you got a report of Tom L and I mixing it up with the old team on Angle Road recently? That was fun and not too hard. Nice to know that I can still do it. I backed off as the Micanopy sprint loomed. No sense in taking any risks. There is no prime as far as I know.

Mostly I have been riding pretty chill Zone 2 rides 4 times a week just to have fun. I figure there is no reason to get into painful stuff if I am not racing anymore. And I am really slow compared to where I was when we rode together, but it is not a big deal since I don't race anymore.

TMonk

Ya I guess you're right. It's that final ~5% that is just so tough to gain... what I'm learning is that it really takes consistency to get my FTP up that last bit.

Also I have been back at it for like ~2 weeks (another week of JRA before that) so I'm not exactly at ground zero here. Regardless, it will be fun to see progress!

echappist

regaining will be easier than building it up de novo

aaronmcd

Yep! Rented a bike, it had disc brakes which felt a bit weird but still had fun on the descent. A good 15 or 20 minutes of the descent was through dense clouds and couldn't ride much over 20 mph. Also, climbing for almost 4 hours straight is insane! It made my leg feel better though.

aaronmcd

Yes of course. Why else would I climb that thing??

Doge

I guess it baffles me why any parent would not steer their kids. That is why we get called parents. Shoot - everyone else including the government want's to steer my kids.

Enthalpic

With anybody else I wouldn't even mention it out of fear of them killing themselves. You on the other hand take stuff seriously and might have the motivation and resources to actually do the testing right.

It's an awesome technique. If you end up doing it you must post the results here... with graphs.

furiousferret

Doge kinda makes sense here.

Enthalpic

People are using the technique very frequently on athletes to model adaptions during high altitude training camps. Altitude camps have downsides so maximizing their usefulness is important. Also you can quickly tell if the athlete needs another visit to the tent/camp after train-low block.

Hermes

Almost signature worthy. Naaahhh.

TMonk

Oh no, he did much, much worse.

TheKillerPenguin

I can't disagree, and he must be digging it considering he continues to perform well and gave up soda on his own.

I had a friend with an altitude tent, I only got to spend a few hours in it but he said he slept with it set to 12k ft every night.
