It’s hard to conceptualize the difficulty of some Winter Olympic sports. Hurtling oneself through a halfpipe on a snowboard, landing triple corks? It must be difficult, of course. Lacing up skates and landing a quad axel looks really hard, obviously. But how hard?If you have no experience in these sports, you can certainly respect what athletes are accomplishing at the Winter Olympics. But it’s almost impossible to have a real feel for it. However, if you’re a runner watching cross-country skiing, you have more ability to understand the history that’s being made at the 2026 Winter Games than you may think.We’re watching Norway’s Johannes Hoesflot Klaebo attempt a sweep of all six Olympic cross-country ski events. He’s won five so far, bringing his career Olympic gold medal count to 10. (The only other Olympian with 10 golds is Michael Phelps.) Sounds incredible, right?…
