she also enjoyed her most successful World Championship performance in Falun, where she took three gold medals: two in individual events (the 15km skiathlon and the 30km classic mass start) and one as part of the Norwegian women's team in the 4x5km relay. Johaug followed her World Championship success with her best-ever World Cup season in 2015–16, winning a second Tour de Ski by overturning a 39-second deficit to Ingvild Flugstad Østberg on the final stage to complete the climb up Alpe Cermis with a lead of 2 minutes 21 seconds over runner-up Østberg. She went on to capture the overall and distance World Cups, rounding off her season by winning the inaugural Ski Tour Canada in a similar fashion to her Tour de Ski win, eradicating Heidi Weng's 30-second lead on the final stage pursuit to take victory by over a minute. Until 2016 Egil Kristiansen coached Johaug, and was described (by media) as "in reality her best coach ... [and he had] helped her master freestyle" skiing. In August 2019, Johaug competed in the Norwegian national athletics championship and won the 10,000 metres on 32:20.87. She followed this up with a time of 31:33.15 in May 2021 falling just 8 seconds short of an Olympic berth. Doping In September 2016, Johaug tested positive for a performance-enhancing drug called Clostebol, an anabolic steroid. Johaug said that the substance came from an ointment for her sore, sunburnt lips, which she used from 4 to 15 September. She claims to have used the ointment called Trofodermin. It contains Clostebol. The word "Doping" behind a 'No Symbol' is normally printed on the back of its packaging in Italy; however, it's not an international or European standardized marking, it's not used in Norway, and some argue it can be interpreted inversely and should instead be an open circle. Johaug said that the drug was given to her by the team's physician, Fredrik S. Bendiksen. Bendiksen said that he did not notice that it contained a forbidden substance. Under interrogation, he explained how in retrospect, a combination of three causes reduced his focus to allow the unlikely mistake to occur: 1) His wife's eye surgery (potentially cancer) had him to have to leave Livigno the next day. 2) Another athlete was hospitalized, 3) He had to prepare for a press conference presentation about the team's asthma medication protocols the next day.
