I read a book by Lauren Fleshman called “Good For a Girl,” and the way she describes racing is like trying so hard you no longer can see color.

For those who have competitively raced, what does it feel like to try that hard and how do you know how hard to push before you throw up or pass out or something?

Two of my non competitive races have had me choking down vomit at the finish but afterwards I still feel like I could have done way more. Is that normal?

Thank you!

Been doing some lactate testing the last year and gotten the feeling and the lactate very close with morning sesions +- 0.1 mmol error, and in the evening identifing when i was without energy (lactate would be way lower and hard to speed up) and when i was feeling good (Going fast, floating, high but controled lactate)

The question:

how do you use it to test what works or not? Or how long does it take the body to see meaningful adaptation?

For example:

Same session before peak was 1.8mmol, after race period and not enough rest same session as baseline session each week: 2.4, 2.5, 2.5, 2.6. Later i realice i was overtrained and these should been a signal,

but now that season starting and getting back to testing by testing each week in same conditions after how much time the adaptation would be greater tham the variance
