In the World Cup, their sport's annual measuring stick, Vonn, 33, owns four overall titles; Shiffrin, who turns 23 in March, is on pace for her second. Vonn has won 81 World Cup races, a record for a woman and second most for anyone in history; Shiffrin is halfway there.
Each claimed an Olympic gold medal in her specialty: Vonn in the downhill in 2010; Shiffrin in the slalom in 2014, when Vonn was out after right knee surgery. Now, with the opening ceremony in South Korea on Friday, arrives the first — and, presumably, last — chance for them to share the spotlight at a Winter Games.
