That’s what I thought, since I got the indoor bike for my spouse, and she loves it.
So I was SHOCKED when I started doing virtual races (with others around the world), competing with them while having my power in watts, FTP in w/kg, speed, cadence, BPM and hill incline data all displayed, and am REALLY ENJOYING IT. The Wahoo app even allows drafting, with watts saved displayed when you are above a certain speed, and at the proper distance behind other riders. And going downhill, you generate speed and can save your energy coasting, just like outdoors. And having the proper line into corners even makes a difference. And just like outdoors, if you lose the pack, it takes a lot of effort to regain and get back on the draft. Very unexpected fun, since I love biking outdoors.
The solo rides, and non-races are TBH too boring for me. So sticking to races and group rides only, and working to increase my FTP, and improve my standings at the finish in these virtual races.
But still looking forward to better weather and getting back outdoors.
