All Olympic canoe/kayak slalom training sessions at Whitewater Stadium have been cancelled on Thursday afternoon due to “technical issues on the course,” organizers announced.

“It was an issue with the pumps on the course,” Miguel Gomes, media officer at Whitewater Stadium, said to NBC Olympics. “It should be fixed today.”

Gomes was unsure if the fix would take 15 minutes or a couple of hours – but expects slalom training to resume on Friday.

Gomes does not expect competition schedules to be affected.
