Thousands of people will be running the Twin Cities Marathon on Sunday. Some have done several marathons, but for many, it’s their first time. After months of training, the last day before a marathon is different for everyone. Mary Lunzer of Stillwater has her routine. “Go for a bike ride, have a nice dinner, go out for cocktails the night before,” Lunzer said. As runners picked up their race packets for the Twin Cities Marathon at the St. Paul RiverCentre on Friday, they were thinking more about dinner than running.
