We find a successful model of chaotic inflation with an inflaton coupled nonminimally with gravity where the coupling constant (Formula presented) runs with the evolution of the inflaton. The running of the coupling is slow enough for natural values of the Yukawa couplings. If a small value of (Formula presented) is chosen at any given scale M, then the coupling remains small enough to have a sufficient period of inflation.
