As described in further detail below, I would like to see a cooldown mode, which would allow the user to start cooling down with the click of a button. As a result, the watt meter should stop simulating ascents, and to avoid temptation, on cooldown Zwift should not count your time on Sprints, and your character’s appearance should tell other zwifters that you are cooling down.
Problem: You are doing a route with lots of ascent meters/feet. You’re done with the training and want a moment to cool down but then that grueling ascent begins again. Oh, and that Sprint does look kind of tempting. And you can’t really let that zwifter pass you.
Solution: Click on Cooldown mode. On Cooldown, Zwift simulates only flat (i.e. no ascents/descents) allowing steady pedaling. Your character does not activate Sprints nor other timed routes. On the downside, you stop gaining ascent meters/feet.
Graphics: Your appearance changes (I don’t know, with a cooldown vest?) to let people know that you are cooling down. The character sips water at regular intervals. May even wave to passers by.
