Just seen on GCN that Zwift has bought Rouvy. Tried them both and opted to keep My Whoosh, but its certainly a talking point for those that use such platforms for training and racing. They have said that they will keep them separate for now, but wonder what the future holds. Personally, I think for what you get for free on MW, massively outweighs the benefits of the other two, but there are plenty of other options too, such as Training Peaks Virtual and Wahoo Systm, to name but two. I think they will eventually merge and price increases will ensue, but who knows.
