Olympic swimmers finally made their jump into the Seine River in Paris near the Pont Alexandre III on Wednesday morning after multiple delays over water safety concerns.

One of the most widely discussed venues for the Paris Olympics was the Seine River as the host of swimming for triathlon events and the marathon swim, but hosting the events was contingent on a costly cleanup effort to make the river swimmable for the first time in more than 100 years. Officials confirmed early Wednesday that the women’s and men’s triathlon events would proceed with swimming the Seine.
