Rupp's mile race this weekend at the New Balance Indoor Grand Prix will take the place of the record attempt next weekend.
Ricky Simms, agent to Galen, told LRC: "The aim for this weekend is primarily to race well and compete. He will not race on the 15th but instead prepare for USATF Champs and World Indoors. He is in good shape and can do very well in Sopot if he gets it right."
