Wesenberg started competing internationally in 2014–15 on the Europe Cup circuit, winning her very first race, at Lillehammer. She went on, with three fourth-place finishes and two seconds, to become the first American woman to win the overall Europe Cup season rankings.[4][1]
She moved immediately to the World Cup for the 2015–16 season, taking 15th place at the World Championships in Igls and 11th in the season rankings. She took her first (and so far only) World Cup podium in 2017, with a silver medal at St. Moritz, and improved her World Championships performance to 13th at Königssee; also at the 2017 Worlds, she was on a team event (combined bobsled and skeleton) squad that finished 10th.[2]
