Organizers of the Twin Cities Marathon said they won't disqualify an 81-year-old runner who won his age group after using a borrowed catheter. Jerry Johncock of Shelbyville, Mich., was sidelined at an aid station about 21 miles into Sunday's race because a blood clot prevented him from urinating. The aid station had no catheter, but a spectator stepped forward to offer Johncock a catheter he had in his car.
