Golf training device for optimal putting speed from various distances and slopes

A golf putting practice device for optimal ball speed from various distances comprising:

• a target cup/hole that's 4.0 inches in diameter with 2 equal loops directly on either side of the target cup/hole with a flag in the middle of the target cup/hole;
• the target cup/hole is adjustable and slides along guiderails behind the real putting green cup/hole and can slide 1 inch to 18 inches past the real cup/hole on two 24 inch long guide rails with inch markings on the guiderails;
• the guiderails attached to a semi-circle anchor which is 4.25 inches in radius and is 1.5 inches in depth sitting inside the real putting green cup/hole;
• the semi-circle anchor is deep enough to provide 1.5 inches into the real cup/hole to allow a putt with enough speed to reach the target cup/hole behind the real cup/hole to have a golf ball fall into the real cup/hole without any effects from the device.
