Saturday's U.S. Ironman Championships may take place without a swimming leg after a break in a sewer line that will lead to the release of millions of gallons of raw sewage into the Hudson River. Triathlon officials were informed Thursday that a rupture in Tarrytown, New York, will require a controlled release of the county's sewage into the river at a point about 20 miles north of the finish line. The first-ever New York City Ironman triathlon has 2,500 particpants who each paid at least $895 for a spot. “We’re not messing with water quality,” race organizer John Korff said. “It is what it is—it’s either yes or no. It depends which way the water is flowing. Athletes will know at least the day before.” The health department is currently advising kayakers and swimmers to avoid direct contact with the water.
