Hi @deb_scott, welcome to the forums, can you let us know what devices you use for zwift and how you connect, bluetooth or ant+? Are you riding in ERG mode or just free riding around Watpoia when this happens?
Also ensure your height and weight are set correctly.
I double checked my height and weight after reading some of the threads. This happens when i am in training mode with ERG on. I am currently just starting out on the Fondo Training plan. My average power on the last ride ranged from 73 to 255. Bluetooth from my Kickr core to Zwift on my mac. Using the Zwift companion too.
I just looked at your last ride, there are a lot of zone 1 blocks where you are going between 60 and 70 watts. Depending on your weight, and if the road is flat or going uphill, the speed could be quite low. I suggest you try a free ride, not a workout, and see how you do on a flat route like tick tock or tempus fugit in Watopia.
