The floor moved slowly at first for around 5 minutes but gradually sped up. It went to around jogging space and I kind of spaces out. It was a nice feeling to run, to move and I lost myself in that feeling. The speed went quicker and quicker until it reached around my top speed. I didn't have a speedometer so I didn't know how fast I was going but it was much quicker than I could have run before. Sadly, all too soon, the system sent a notification.
