Riding on the trainer can be a drag for the most part, but my coach Adam and I have found a way to implement it into training and filling in what we can for racing with Zwift racing. The main Zwift race I do is the Driveway Series because it has great competition, a good course, and has the right distance to get in the perfect workout. This past Driveway race I got 2nd place after managing to make it with the group constantly covering attacks thinking a small group would get away to the finish. I definitely recommend doing some Zwift racing to help your training and help fill the competitive nature we all have in these times of no real world racing.
