Additionally, the in door training enables interruptions that you would not otherwise deal with when out on the bicycle.
The phone rings, an email pops up, the mail truck drops off your stuff, neighbor knocks on the door holding a freshly baked pie in her hand, some yankee goes on your lawn, animal starts dropping a hot load in your shoe. All these are factors that can distract you from being a spartan on the trainer
