2024 Paris Olympics triathlon mixed relay held despite Belgian who swam in Seine taking ill

Olympic triathletes plunged into the Seine River Monday morning as the mixed relay event got underway after organizers said the bacteria levels in the long-polluted Paris waterway were at acceptable levels.

In a very close sprint finish, the team from Germany won the gold medal, with the United States taking silver and Britain clinching bronze. 

The plan to hold the swimming portion of the triathlons and the marathon swimming events in the Seine was an ambitious one. Swimming in the river has, with some exceptions, been off-limits since 1923 because it's been too toxic.
