After a long time off (kids, job requiring travel), restarted in 2014 because having lost 30 pounds walking with my dog I had plateaued on time & calorie burn. Started doing spin class twice a week at the gym. Made friends with a guy that invited me to ride on the metro bike trail, and that got me hooked on riding outside for the second time in my life. FWIW I spend as little as possible riding indoors, the weather is nice here in NorCal and there is a large network of bike lanes and paved trails to ride on.
Spoke with one of my Peloton addicted neighbors last week, she loves her Peloton Bike+ and fitness classes, and would never ride on the road. A friend that only rides Peloton for general fitness, he lives adjacent to the bike trail and can ride over 60 miles without any cars, but he doesn’t ride outside. My brother-in-law lives in a gated golf community, more golf carts on the street than cars, but he drives (golf cart) 1 mile to the gym and warms up on an exercise bike.
