It was this hot during the women’s 4 x 5-K relay at the world nordic ski championships in Seefeld, Austria, yesterday: So hot — temperatures well into the 50s and skiers fighting through slushy, slow snow — that Therese Johaug, top, Norway’s number one skier, collapsed into an instant on-snow cooldown at the finish line. She (and Norway) finished second. Jessie Diggins, the top US skier, below, cut the legs off her race suit and rolled down her striped red, white and blue relay socks. The US was fifth.
