Career
Lif lives in Östersund and represents Lima Biathlon. Her trainer is Roger Westling. Her first international meet was the junior division of the World Championship Summer Biathlon 2007, in Otepää.
She competed at the junior level in the IBU Cup (formerly the European Cup) beginning with the 2007/08 season, and in 2009 competed for the first time in the Junior World Championships at Canmore, where she came in 34th in the sprint, 33rd in pursuit and individual, and with Ingela Andersson and Marielle Molander, 9th in the relay.
The following year in Torsby she placed 40th in the individual, 30th in sprint, 33rd in pursuit and 12th in the relay. In 2011, competing in her third Junior World Championships at Nové Město na Moravě, she was 25th in individual, 34th in sprint, 41st in pursuit and 14th in the relay.
At the start of the 2012/13 season she made her first appearance in the World Cup, in Östersund, where she came 88th in her first sprint. In her next sprint, at Hochfilzen, she placed 61st, missing qualifying for the pursuit by only one position.
In the relay, as last runner after Elisabeth Högberg, Anna-Karin Strömstedt and Elin Mattsson, she shared 9th place.
Between 2008 and 2010, Lif also competed in several international cross-country skiing events at the junior level and lower-level International Ski Federation events. In April 2014, she was not included in the national squad, which she attributed to problems with a leg and a disc that would prevent her from fully following the training programme.
