So you want to ride indoors.
Maybe you want to try Zwift, or maybe you are over Avatars and want to focus on pedaling and doing work and not paying another monthly subscription
I will begin this article by reminding you that you are SMART and that you always have the option of riding indoors, exactly like you do outdoors. Shift/Pedal and Use your HR/Power and FEELING (RPE) as relevant.
I will second this by asking you to re-read the above thought and keep it in mind when any program crashes, you aren’t hitting the perfect intervals (what is a perfect workout?), or you spend more time setting up and looking at screens then pedaling.
