The encounter came as part of the couple's royal tour of Poland and Germany, which earlier this week saw them visit the site of the Nazi concentration and death camp at Stutthof in Poland.
Before the start, Kate was heard to tell her team: "No pressure but I do want to beat my husband".
Crowds gathered to watch as the royal couple coxed opposing teams in the contest on the River Neckar, commanding crews made up of rowers from Heidelberg and its twin city, Cambridge.
But while we never see her with a touch of hair out of place, the Duchess of Cambridge isn't as confident as we all think.
Despite her advantage, Prince William's team, which was made up of amateur local rowers, managed to win by almost an entire boat's length.
Sky News reported that the royal couple signed the visitor's book and said, "We were intensely moved by our visit to Stutthof, which has been the scene of so much awful pain, suffering, and death". Dressed in a bright yellow lace dress and a handy apron, Kate dived right into the pretzel-crafting process, while it took Wills a bit longer to catch on.
William and his wife Kate then met with World War II veterans at the museum to the 1944 Warsaw Uprising against the Germans, and traveled to a business center where they met with representatives from Polish and British business. Afterward, both royals wore medals as they participated in a beer tasting by the banks.
He said: "Kate and William are excellent young people - they know, they understand European young people everywhere".
The couple wasn't afraid to roll up their sleeves, hand-crafting pretzels and sweets with local apprentices.
Prince George and Princess Charlotte have been stealing the show since the star of the royal tour, but tonight, it's Kate's turn. "George is more laid-back", the source reportedly said.
Whatever the case, it didn't seem to phase Kate and Wills who were keeping to a busy schedule as they whip through their five-day tour of Poland and Germany.
