After nearly 15 years with a “dumb” trainer, I bought a Kickr Core in January. I have over 500 “trainer miles” since then. I haven’t been outdoors in 3 months on the bike. (A bunch of snow shoeing!) I like the ability to do a structured workout and the smart trainer can provide the changes automatically to the workouts to achieve the desired affects. This is the first winter of not getting out at all, but since the new hip, I don’t have the same confidence out there I once had. Warming up this week, and with daylight savings time, after work rides outdoors will begin this week. I signed up for a “gravel ride” taking place the end of April so I need to get used to shifting and steering again, ;-)
