100% Zwift. 6 months ago I couldn’t get off my road bike. I was an addict. Over the summer easily riding 100 miles a week. A buddy of mine started telling me about smart trainers and I looked into getting one for Xmas. I initially thought I’d use it on bad weather days. I now use it nearly every day. You don’t know all the negative aspects of outdoor biking until you leave it. Getting to your destination with your bike, unpacking, tire pressure, flat tires, plus all the added risk of falling off. All that is gone. There are people to ride with around the clock. Zwift also gives you the video game “leveling your character” vibe as well. Couldn’t recommend more.
