“A bunch of 30s Hills” dang… you just stole my whole training philosophy
Eat yer carbs
Restricting carbs after a glycogen-depleting workout nearly doubled peak fat oxidation during a workout the next day.
It also shifted Fatmax from 41% to 56% of VO2 peak.
But it came with a cost…
a ~7% drop in maximal power output at a higher perceived effort.
And low-glycogen training didn’t enhance markers of mitochondrial efficiency or energy production.
"Cardio moved it more ... with lifting adding nothing on top" — interesting
The benefit of lifting weights stops growing after about two hours a week.
90 to 119 minutes a week went with 13% lower risk of death from any cause. Above 120 minutes, there was no extra benefit.
Researchers followed 147,374 nurses and other health workers for up to 30 years and recorded 35,798 deaths. The same amount of lifting also went with 19% lower risk of death from heart disease.
People who did plenty of cardio and also lifted did best of all, with about 45% lower risk than people who did little of either.
This study shows a link, not proof. People who lift may also have other healthy habits.
What this means for you: you do not need to live in the gym. About two hours of strength training a week, on top of regular cardio, covers most of the benefit.

Most stress comes from the things you’re trying to avoid, not the hard things you’re actually doing….

Advice is usually given by a person who has made a mistake and doesn’t want you to make the same one. Maybe listen before you take action:)

My observation will save you time and energy
As we age, athletic performance becomes more and more simple
On this platform, I watch the same conversations being held, over and over. The answers you seek will be discovered by doing.
A good listen on this topic is Brownlee talking to Frodeno on Going Mental

Why decide in advance how many intervals to run? Do as many quality reps as possible, then stop when form or pace deteriorates.

People understand the world via stories.
In sports, we label some athletes heroes and others villains. Sometimes those labels are warranted.
This time it isn't. Henri did exactly what he should've done—he (heroically) won the race!
The Brownlees' heroics don't make him a villain.
This consumed me for 10 years. Online abuse is not okay.
It has made me doubt myself and my abilities for long enough, it was time I spoke out and let it go!

"When oxygen is the limiter, carbs win"
Classic research: Six days of keto eating and race pace cost these elite walkers 5-8% more oxygen. The high-carb group all improved and 6 of 7 keto walkers were slower.
Burke et al.'s 2021 study put 13 world-class male race walkers in a supervised training camp on keto or high-carb, then raced a sanctioned 10,000 m. Here's what the research actually says.
Fat burning did exactly what keto fans claim. In the keto group it climbed inside 5-6 days, matching rates seen after 3-4 weeks on the diet. Peak average fat burning hit 1.43 g per minute, up over 200%.
But race pace started costing more oxygen. The authors' own summary figure is a 5-8% rise. Part of that is chemistry: burning fat takes more oxygen than burning carbs. Their caveat is that the loss of economy at high intensities looks bigger than that chemistry alone explains.
Then the races. The high-carb group improved across the board, 5.7% faster on average. The keto group went the other way: 6 of 7 walkers slower, 2.2% on average.
A carb reload didn't undo it. A full high-carb day plus a carb meal two hours out only brought carb burning back to 61% and 78% of baseline at race speeds. The muscle kept its fat-burning retooling, the higher oxygen cost held, and the performance didn't come back.
My take: when oxygen is the limiter, carbs win. I wouldn't go keto into race week.
Follow for more research breakdowns.

“we will pay any price….to assure the success and survival of liberty.” Is this still true? Do we prize liberty or do we prize power and purse? No more clear test than the choice between Ukraine and Russia. Abandon Ukraine and we abandon liberty. Eventually even our own.

Don’t get stuck in comparison mode.
Don’t look fondly at the glory days and think that they hold some secret to success. It worked in that moment. That moment is now gone. Focus on what you can do in the moment to get better.

Before my first and only real race/half last fall I read a study where most people didn’t finish 30-40% of the gel in the packaging (not on purpose but they just tossed a lot). I just did a 23g carb gu every 20-25 min (my stomach doesn’t tolerate much at once spaced is best for me) but was really careful on race day to consume the entire gel. I know the adrenaline of a race environment helped but I had so much less fatigue in the second half than any long run I ever had up to that point and I went and did a big hike later that day carrying my son and noticed I felt fine. I share this just to say I used to feel kind of silly training myself to consume carbs on a 6-7 mile run building for a half but part of durability I think can be perceived fun and enjoyment. After that race I wanted to run 90 minutes on Sundays instead of 60. I adopted making sure I was getting the whole gel in going forward and doubled by 1/4 cup of morning long run oats to 1/2 and found longer runs were just more fun. My slow mom miles two cents. :)
