My clients and I have noted that when using Zwift on a TrainingPeaks workout, this week, the ramp from low to high power interval seems much faster(nearly instantaneous) than the usual ~3 seconds. It has been like hitting a wall on the very high power targets. Has there been an update that isn’t listed?
Resistance changes on the ramp from low to high power intervals is something typically controlled by the smart trainer. So if you’ve noticed a change, it’s likely the result of a smart trainer firmware update, and not something Zwift has done in one of our updates.
However, if you’d like us to investigate the matter further, please submit a support ticket and one of our Zwift support team members will be happy to assist you.
