I've got mine downstairs in the spare room, but with the fan on (to keep the sweat at bay .... nice!) it was creating a chill draft straight down my chest. Tried riding with no fan but then I was just overheating. Can't win Just had to make sure not to push too hard and keep my breathing relaxed. Bit wheezy now but should settle down Legs, on the other hand, need a lot more time to recoverI've brought the trainer down from the loft so a lot warmer now in the dining room didn't want to risk it again up there
