Zakrzewski was stripped of her third position in the GB Ultras race in 2023 when it emerged that she took a car ride for a part of the race. She categorized herself as an "idiot" for accepting the award and blamed it on miscommunication as she claimed that she originally intended to withdraw from the race and hence took a car ride. [12] However, the race director, Dwayne Drinkwater, rejected these claims noting that "After the event, there was no attempt by Joasia to make us aware of what had happened and to give us an opportunity to correct the results or return the third place trophy during the course of the subsequent seven days."
