I’d second Sufferfest. Zwift is a virtual ride around Richmond Park, Sufferfest has real humour, and you used to be able to but the videos, but now have to stream them. The Strava app also has training videos. They are road orientated, but don’t let that detract.
Since a turbo has no wind resistance, speed of wheel is related to power output. So these apps use a bluetooth or ANT speed sensor to convert to power (obviously it has to be on the back wheel 😉 . You can also link a heart rate monitor and cadence. Smarter trainers have these sensors built in. Really smart sensors will control resistance automatically.
For apps, the phone is a little small if you have middle aged eyesight and are in a dark garage 😉 . I use an iPad mini, and that is pushing it. The nice thing about a phone is the mounting option.
So if you want the full experience, I’d recommend the Wahoo Tickr HR monitor, speed and cadence sensors (all bluetooth and will talk directly to phone). Download Zwift and/or sufferfest apps, try them.
Yes they are boring, bur Sufferfest can keep me on a spinning bike in a hotel away from home for 2hrs at a time.
Zwift, I’m less excited by; it’s trying to be too real – speed in Zwift land is related to power and “terrain”, so if you are turning out a virtual 200 Watts, and it’s telling you you are climbing a mountain, your Zwift speed will be slow 😉 . You can race too, but I prefer that in the real world.
Have fun, it’s bad, but some people ride on a turbo almost exclusively. And I hop you recover well.
