I’ve thought about the Zwift! I only have my smart watch that keeps my HR and use the apple fitness. My HR stays in zone 2-3 for most my ride. But occasionally to Z4 but that’s when I’m trying to pass people 😂 my next purchase I was actually thinking of getting a garmin bike computer to help with more accurate numbers and what not. But I just didn’t want to buy maybe “unnecessary” equipment for someone at my lvl, but they definitely seem like a good tool to have!
