Disclaimer: I am not affiliated with the app/software, just a new user who is looking for alternative to Zwift and riding “real world” routes.
I just discovered a new virtual cycling app/software that lets you upload and ride real world routes. Think of “Magic Roads” by the software formally known as RGT.
Sure, the graphics are not as immersive as Zwift, but it is sufficient for me. Helps that you don’t have to download a new software for it. You can just run it off the webpage. Currently using it to ride (virtually) all the categorised climbs of La Vuelta 2024.
Check it out at www.biketerra.com. Hope you have as much fun on it as I am having.
