A portable toy vehicle racing set for use with at least one toy vehicle having a motor includes a case having a first section with inner and outer surfaces and a second section with inner and outer surfaces. The case sections are pivotally coupled together to permit movement between opened and closed positions. In the closed position, the set simulates a carrying case. In opened condition, a flat track surface is presented. The first and second sections of the case include predetermined track layouts which provide a closed loop track. The closed loop track defines at least one lane in which the toy vehicle can ride with the at least one lane including contact rails for supplying power to the toy vehicle motor.
