What’s Joey McIntyre doing to get ready for the New Kids on the Block’s upcoming tour with 98 Degrees and Boyz II Men? Running, apparently. Over the weekend, Joey Mac hoofed his way to the finish of the Kaiser Permanente Rock ’n’ Roll Pasadena Half Marathon, which was a benefit for CureMito. We’re told that McIntyre’s run included a few stops to snap pictures with fans. Other celebrities on the course in California included Chandra Wilson, Sandra Oh, and Justin Chambers from “Grey’s Anatomy,” as well as Sean Astin of “Lord of the Rings” fame (above right, with McIntyre and actress Andrea Barber).
