I had a successful Ramp Test this morning, however the speed seems to be the same throughout the test which does not seem correct. The test shows that I covered 10.9 km, but there is no measure of distance per segment. Without the correct speed it is impossible to measure the distance per minute/segment. The speed locks in at about 26kph for almost entire test.
Speed and distance are often misleading in ERG. It’s best to ignore it really.
The trainer sends speed data according to the flywheel speed, so at the same wattage lower gear = slower and higher gear = faster. The only way to get a somewhat reliable speed reading is to build speed calculation based on wattage and weight.
Technically you covered 0.0 miles
At zero miles per hour.
If you’re worried about speed and distance go and ride you bike outside.
Unless you changed cadence and/or gearing, the measured speed will remain constant. There is no “ virtual speed” calculation in TR like in Zwift, for example.
For Wahoo devices, in the Wahoo app there is Erg Mode Speed Simulation. When this is turned on the speed and distance is relative to your power/watts and not gears or flywheel speed. So when uploaded to Strava you will get distance and speed that is close to riding outside on a smooth flat road with no wind. Compared to my outdoor rides it’s “close enough” to be fairly representative.
My ramp test yesterday had a NP of 240, max power 402, covering 7.67 miles with an avg speed of 18.3 mi/h and max speed of 24.8 mi/h. My “speed” graph tracked linearly with each increase in power aside from my cadence. That being said, speed and mileage is not a good metric to keep track of and Iike others have said, it’s kind of irrelevant.
