Elana Meyers Taylor is halfway to her second world bobsled title in three years, but two other Olympic medalists are within five hundredths of a second of her.
Meyers Taylor leads by .02 of a second over two-time Olympic champion Kaillie Humphries of Canada after two of four runs in Koenigssee, Germany, on Friday.
U.S. Olympic bronze medalist Jamie Greubel Poser is third, .05 behind.
The final two runs are Saturday (9:15 and 10:45 a.m. ET, NBCSports.com/live and the NBC Sports app).
In 2014, Meyers Taylor led the Olympics after each of the first three runs before being passed by Humphries in the fourth and final run by one tenth.
