Read our privacy policy A test run meant to allow Olympic athletes to familiarize themselves with the marathon swimming course in the Seine River was canceled Tuesday over concerns about water quality in the Paris waterway. The portion of the Seine in which the triathletes swam is much shorter than the course for the marathon swim, which has races scheduled for Thursday and Friday. World Triathlon released data Tuesday showing that when the triathletes swam Monday, the levels of fecal bacteria E. coli and enterococci were within acceptable levels.
