Under desk/bed treadmill (Plymouth)

Hello all, I have signed up for a fundraiser to assist veterans obtain dogs for ptsd and other things I am walking a mile a day in February. Here’s the issue it’s cold out there, no i do not have an issue with that but when it snows or when it’s bad out I can’t walk and will lose the day. I’d like to stay on track and this all begins on the 1st, I know late request. If anyone has one they no longer use and it works I’ll quickly pick it up. Thanks in advance ( I ask for under bed or desk due to having a very small space thanks)
