Vonn said:"It’s really hard to be away from a sport for six years and then come back to it and be at a competitive level. And I think with speed skiing, it takes a lot of knowledge of the sport. It takes a lot of runs on the tracks to really get to know them well."The 40-year-old also shared that her experience and age give her the know-how and an advantage over younger racers. She added:"I think that gave me a competitive edge. And the same with Cortina. I will definitely be the oldest but also the most experienced on that track. So I think that gives me a slight advantage. And, you know, of course, I'll have my disadvantages. But I think that in ski racing, the knowledge I have is a lot more impactful than perhaps in other sports."The 2026 Milano Cortina Olympics will take place from February 6 to 22 in Italy, and Vonn will have her sights set on ending her career with an Olympic medal.
