If weather was enabled for everyone I would have to signup for a much more expensive package with the weather data provider and Intervals.icu servers would be under heavier load and so on. So that is one of the reasons why it is a premium feature. It is a similar story with the upcoming routes feature.
Also I need to persuade more people to become supporters somehow. Intervals.icu offers a great deal for free and I don’t want to take any of that away.
What I am going to do at some point is make it possible for people to “sponsor” other athlete’s. Then you could pay for your athletes and recover that into the fees that pay you.
Thanks for supporting Intervals.icu!
