Maybe you want to run some experiments on Zwift. That’s when you’ll need a way to automagically submit power and cadence to the system. Such a device is often known as ANT+ simulator. I’ll not enter in details of the actual set-up unless requested. You also would hopefully clear the field of drafti…

[|45x45] Lee Lee_Proctor_B 1 5d I did this even t at 12:30 on 4th April. I loved the TT format but I’m totally confused by the Zwift physics/algorithm! For my event I rode a steady threshold pace and average 325W, I came 5th overall in a time of 1:13:05 I weigh 88kg so my average power/weight w…

Lin Lin_Alan 4d It’s not pancake flat. It’s not necessarily the greatest W/kg that wins. It’s not necessarily the greatest raw wattage that wins.

[|45x45] Gerrie Delport TeamODZ Gerrie_Delport_TeamZ 4d Height appears to be a factor? Height should be the main factor on a TT flat race, height is used to calculate your Cda (frontal drag area)

Bhaltair B_Gru 3d For a pan-flat course brute power should outweigh power/weight like it does IRL. It’s pretty much w/kg on Zwift. Well, that does explain quite a lot… As a heavier rider, I fully expect to struggle on the climbs. But I also expected to have some advantage on the flats, and t…

Paolo Paolo_Cecchini5714_Z 23h Control: 170 cm, 70 kg, 250 watts Test 1: 170 cm, 85 kg, 250 watts (What’s the time difference?) Test 2: 170 cm, 85 kg, 263 watts (Does that equalize the times?) Test 3: 175 cm, 85 kg, 266 watts (Add 5 cm, is the time the same?) Lead in Finish Line Lap Time …

Bhaltair B_Gru 22h Awesome! Clearly Zwift is not using the Cycling Power Lab formula. We should probably also consider rolling resistance, but going from 70 to 85 kg, rolling resistance should only increase by about 2%, so that won’t account for the difference. If I have some time I’ll try to fit…

[image] Paolo_Cecchini5714_Z: If I have some time I’ll try to fit your data to some equations and calculate the power increase (according to Zwift’s physics) that would be required for a 175 cm 85 kg rider to keep up with a 170 cm 70 kg rider. And the answer is … Phrases from The H…

[image] Paolo_Cecchini5714_Z: I guess you’ll going to land on nowhere with Cycling Power Lab formula. You’re right about that. I used equations to include aerodynamic drag and rolling resistance in a steady state. I neglected the 16 m elevation gain at 1% since I figure that makes a 0.01 wa…

Hi I don’t know if this thread is still active but I have recently downloaded an ANT+ simulator from the thisisant web site and I’m struggling to get it to communicate to ZWIFT. I want to simulate power however I have absolutely no idea how to use it Thanks

what do you want to do with a simulator? I would steer clear of using simulators.
