The fictional Ironman of movies can fly; Madison drivers probably would like that ability on Sunday to avoid congestion and delays when the Ironman Wisconsin triathlon hits the streets. Close to 3,000 of the world?s best athletes will be in Madison on Sunday for the 12th annual Ironman, which will push city buses out of downtown and cause traffic delays downtown, on the UW-Madison campus and along the 112-mile bicycle race route.
