My favorite paragraph here:
Instead of offering us distraction — the glittery melodrama of figure skating or the quirky novelty of curling — cross-country skiers lean right into a bleak truth: We are stranded on a planet that is largely indifferent to us, a world that sets mountains in our path and drops iceballs from 50,000 feet and tortures our skin with hostile air. There is no escaping it; the only noble choice is to strap on a helmet and slog right in. Cross-country skiing expresses something deep about the human condition: the absolute, nonnegotiable necessity of the grind. The purity and sanctity of the goddamn slog.
