Sudden Sprinting on a Trainer only gets my avatar to slightly increase his speed


(.Jason Perez Recumbent Dork) #1

So I’m rolling along at 24mph on flat ground at 250 watts then I drop down a few cogs and sprint at 600 watts for 15 seconds but my avatar with only slowly increase his speed to maybe 27mph. I’m brand new to zwift and I’m using a Tacx neo, is this normal?

I know in game speed is based on watts/grade/weight instead of direct trainer speed but the reaction to sudden all out attack just seems broken.

What do you have your watt smoothing set to?

Sorry if this sounds ignorant but are you referring to the two choices in the zwift ride menu that are ether instant or 3 second smoothing? I have that setting at instant so it gives me exact power. If your refering to something else then please enlighten me. I will say that my power numbers in zwift are very responsive and can jump several hundred at a time when I sprint but the change in my MPH readout is very slow.

That is what I was referring to.  What trainer are you using?


(.Jason Perez Recumbent Dork) #5

Tacx Neo

Do you use ANT+ or BT?


(.Jason Perez Recumbent Dork) #7

Ant+ to my windows desktop right now, even got the usb extended cord for the Ant stick. I’m not even sure how to do Bluetooth on the desktop.

I am on a Tacx Bushido and have the same feeling (at lower wattages than you). I feel like in Zwift I accelerate from a stop slower than I do in the real world. Same goes for any instantaneous change to a significantly harder effort. It is from a stop and also from moving to a higher effort moving.

In the real world there are small hills I ride all the time and when I get the right gear to be able to hit them with a quick cadence and a fast boost of power, it seems to me that I accelerate a lot faster than if I do the same on a small Zwift hill.

 

I have not studied my GPS tracks, however. Maybe it is my perception and not the reality.

Have you actually looked at a Strava recording of the a real world ride vs a Zwift ride? I will try to remember to do that myself.
