There is another thread discussing this but for people that primarily ride indoors we are going to make some changes. If you say long rides indoors your shorter rides will be limited to 90 minutes and your long rides frequently weekends will be split into multiple rides with max length of 90 minutes.
Our chief scientist Andrea Morelli says indoor movements are too limiting and ergonomically unhealthy when sustained but he says breaking this into smaller rides with breaks in the middle helps mitigate much of the problems related to spending more time on the bike in a single day.
Below shows the idea of how you turn this on or off. Hopefully this is ready by Oct 5th.
