You are already stuck to Zwift’s race schedule anyway. You can either turn up for any of the existing races or you cant based on your real life commitments.
Again there are multiple ways of doing it technically and as TT’s are 1 minute intevals starts, you ‘could’, when signing up for a TT event specify preferred start times around the start and end times of the TT event and get a preferred start time suited to your needs. Again this is all nitty gritty detail thats getting ahead of the actual idea.
Zwift is attempting to re-create real outdoor riding, indoors. I don’t see them trying to create mario-kart for bicycles??
Again, TT’s are not a mass-start type event. I guess, personally I’m looking for indoor races that mimic what I race in real life as a way to race when the weather is s**t and I want that feeling and competitive boost of pinning a number on my back and being alone on the road chasing down my minute man. (and not just firing up TR and doing 2x20)
Just going full gas around watopia for 20 minutes with 400 other people in a huge peleton is not my idea of a TT…
Don’t get me wrong it could not work in the virtual indoor environment, but that’s not for any technical reasons.
