That's a good theory, but from my experience there's a lot of individual variation regarding on-bike feeding. I ride with a fellow who doesn't eat on a 3 hour ride and will only drink 1/2 bottle in the summer. He'll have a couple gels before the 4th hour. OTOH, he has a lot of trouble on longer rides because he isn't used to eating and drinking. I will start to bonk if I don't keep it coming on any ride over 2 hours, meaning my HR drops off and I lose power. I have to go through at least 750 calories on a 4-hour hilly ride and drink the usual bottle/hour. It feels like the early glycogen is more available than glycogen later in the ride.

I am the same way. I have friends who barely eat but I need to have a nice pre ride meal and then eat once an hour. Perhaps being my size I do not have as much on board storage or maybe I am crappy at conserving energy. Anyhow... I eat more and perform better.

Personally, I am more successful at dropping weight at the fat lazy person zone. My appetite increases exponentially at higher intensities.

Since FTP is defined as the maximum power you can make for an hour, it's not possible to do 3-4 hours at FTP.
Also the choice isn't between "sugary drinks" and nothing. You can eat other foods while riding.
You're right that sports drinks are over promoted and over used by some people.
What and when you need to eat is highly individual. It also changes with training. Six years ago 2 hours without calories was about my limit. Now I can do three and not be that hungry. I'm about the same speed and fitness, maybe a little faster, but six more years of training has made me better at burning fat.

I can ride for ages at Z2 without eating but I fail to see the benefit.
As soon as I add in intensity my nutrition requirements completely change.

Using a well-known W/kg chart, an average FTP for a "Moderate (e.g., cat. 4)" 150 lb male cyclist is 3.29 W/kg = 224 W. 95% is 213 W, or 770 calories/hour. Of these, 250-300 should come from fat. If you start with 1500 cal of glycogen, 1 hour at 95% FTP should deplete the stores by about a third.

Anyone doing 3-4 hr rides @ 95% of FTP likely has an underestimated FTP.

You asked, "Are you talking biomechanically or physiologically? Having replied that I don't know what biomechanical efficiency means, how is it plausible that I could have been talking about it? If you don't like my answer, you can tear up my bill.

I just read that it is a myth that you should drink before you are thirsty and if you wait until you are thirsty it is "too late."
There apparently drinking when you are thirsty works just fine. And slight dehydration has no adverse effect. In fact, if you drink to completely prevent dehydration you can end up over hydrated resulting in diluted electrolyte levels in the blood.

I thought someone might call me on just reading this. But I am new to all this training stuff so I am just reading about everything. And, even if the news is old the myth remains because I have heard it several times in the last few months when starting to read about this kind of stuff.
