Back in my day, all road bikes were considered endurance bikes. Some with a aggressive or race fit. And some with a relaxed or touring fit. Those race fit bikes are made to endure 100 - 150 or more miles of riding with no load very fast in a single day. Touring type road bikes were made to endure those long rides with a load equipment and clothes for days away from home.
