I am not giving Peleton the win I am just saying that it is pretty slick interface for getting a work out and making you sweat without the small headaches of integration on Zwift etc. That said - if all I want is to improve my cycling, Peleton doesn't help me in the same way. However if I am trying to stay fit with small workouts and lots of variation in the off season - its perfect.
6 months from now I'll figure out which one gets the W.
Curious to learn more about maximizing the use of a very expensive hardware (for me).
Yes though your point is taken - this is definitely expensive hardware in both circumstances. Both have addictive (in a good way) qualities to tie you back into coming for more. Normally I would say that as a negative thing but in this instance it is a good thing.
When I was training for races I would want to be primarily on my bike, but for just offsetting my Oreo addiction the Peloton is perfect.
Zwift, Trainerroad, etc. are good for people looking to train to become better cyclists. You do largely need to bring your own setup, which can often be complicated (although you can then get a setup that mirrors your outdoor work).
I am referring to fitness training, not training to become a better road cyclist, and I suspect most people that use a Peloton or go to Soul Cycle have no intention of training to become better at road cycling. They are doing so to become fitter, and Peloton's training is specifically aimed at improving various areas of fitness. So when I refer to training, I am referring to training to improve specific fitness goals and not training to become a better cyclist.
I have no interest in becoming a good cyclist, but I am looking to improve my fitness across a variety of metrics. I also weight train and do other stuff, but I have found the Peloton approach to indoor cycling well suited to helping meet specific fitness goals.
Peloton caters more to general fitness types with a "spin class" approach using "instructors" and their slick hardware and ecosystem. It's probably a better choice for people who aren't cyclists.
Zwift caters more to dedicated cyclists who typically use Zwift to augment their outdoor training routines with indoor time (avoiding weather and timing/safety issues etc). Cyclists use their own bikes since they're fit for the rider, with their own (more accurate) power meters, etc. Zwift also considers weight, bike aerodynamics, etc. in sort of a "gamified" virtual representation of cycling.
TLDR; Peloton is a group of people riding Peloton machines in "virtual spin class" while Zwift is a group of people riding their own bikes indoors, most who also ride outdoors on Strava.
