Frida Karlsson leads the Tour de ski by far ahead of this weekend's decider and easily advanced from today's sprint prologue.

Karlsson, who is no sprint specialist, was even the best Swede in the qualifiers, fifth overall.

Anna Dyvik was the second best Swede in twelfth place, 3.95 seconds behind the qualifying winner.

For Sweden's biggest sprint star in the competition, Maja Dahlqvist, it was a bit more difficult.

She moved on as 19th rider, 5.73 seconds behind.

Moa Ilar (15th) and Märta Rosenberg (22nd) also made it through the qualifiers, which means that all five Swedes will run in the quarter-finals.
