Yet Velo Vol was ready to throw dirt on my casket because of a couple of eggs. Protein. It's important.

Carbs are fuel, but it's no excuse to binge on them. Reading pre-century advice, and the dietary suggestions I see, cause me to shake my head. If people only realized what they had in the bank, they wouldn't need a triple x sized jersey to store their 4 course meal they plan on eating every hour.

First, when you're in Workout Mode, Erg or not, Zwift doesn't change resistance to match 'terrain'. It's either flat, or in Erg mode it adjusts the resistance with your cadence to match the specified power output for that section of the workout. So, you could be on Alpe du Zwift and it would seem flat, in Workout Mode.

SO, if you did the Ramp Test without Erg Mode, you'd just have to keep shifting gears to increase resistance, just like with a dumb trainer, but your trainer would be providing Zwift with your power output.

The other thing is that you can also change how closely the trainer tries to match the terrain. It's under "Settings" on Zwift. You have to be In Game, in a world. Click Menu, then Settings. Default for Trainer Difficulty = 50%, so it will mimic a 3% gradient when you're climbing a 6% gradient in the game. I generally run it at 100%, since I'm trying to mimic riding in the real world, but if I were to try Alpe du Zwift, I'd probably cut it to 50% the first time.

Two things about Trainer Difficulty - First, even set to 0%, so everything seems flat, your speed In Game is STILL determined by power output, gradient, weight, and aero profile, so if at 0% Trainer Difficulty on a 15% gradient, you might be spinning easy, putting out 150W, and feeling like you're on the flat, but you'll probably be going 2 mph.

Second, on descents, Zwift only mimics HALF of the descending gradient. So a 6% descent is really only 3%, at 100% Trainer Difficulty, and at 50% it would only be 1.5%.


Mind officially blown!!!

Fuel, but tasty, tasty fuel. :love:

True, except you can make your own carbs from fat and protein and the brain only requires something like 30% glucose in the energy mix after a few days of adaptation to carbohydrate restriction. Technically, therefore, you can live on very little carbohydrate, like Shackleton's men, who survived in good health for months on a steady diet of seals and birds and then had the energy to make an arduous ocean crossing in an open boat and trek over the snow-covered spine of an island.

Then, of course, a bunch of them died in WW1. :(

And I bet he'd be super pleased with weighing a buck-forty. He'd make short work of those coastal VA hills. :p

Yeah, but they only managed to pull though that on the promise of chocolate croissants upon getting back home.

Prolly.

He has a point, LAJ - just think of how great you'd feel and perform on the bike if you possessed the vim and vigor of Velo Vol.

I enjoy everything in moderation. Including moderation.

I just did a Zwift workout on the London Loop and just peeked at the leader board. The KOM? I mean, come on. I'm sure that the rider is very strong, but his 2016 ride was 18 minutes and change and his average power for the duration is indicated to be 546w.

I suspect an eBike.

I would think that, in 2016, this was wildly enthusiastic zPower estimate on a dumb trainer. Whatever the case, 18min at 550w just isn't on this side of reality. I mean, if you work backwards from Wiggins' hour record (was that 440w?), you're not getting those kinds of ~20min figures.

Ahh. Yes. I missed the 2016 part. zPower on a dumb trainer makes sense for those numbers.

I'm betting that's a low estimate.

It's possible. That is from Zwift. And when I ride with my friends on Zwift, I am often dropped and once dropped, I can never get back. On the road, I have no problems keeping up with said friends and have no trouble dropping most (if not all) of them on the longer hills. That said, I am not "training" for anything other than fun rides. I don't want or need a power meter for my goals.

Give yourself 10% for the road. I have the same trainer and that's about my delta. My numbers are little higher, but I am training for the Ol' limp dicks.

But what's more fun than crushing souls? :foo:

I crush my friends' souls on almost every significant hill we have. That's good enough for me. They usually catch me on the way down because (a) gravity and (b) I descend with caution.

What's this crushing of souls of which you speak?

Yeah. Its great that Zwift can find your FTP from a ride, but can't really tell if your data is questionable.

I do remember early on, seeing some people I ride with IRL, on Zwift with just amazing power numbers, knowing there was just no way. And yes, it was dumb trainers and Zwift's interpretation of power.

That's a great point! I'll work on it.
