The final miles of a nearly two-month race across Antarctica — a lonely effort marked by long days, short nights and stunning endurance — ended Wednesday with a sprint to the finish.
In an effort that could go down as one of the great feats in polar history, the American Colin O’Brady, 33, covered the final 77.54 miles of his 921-mile journey across Antarctica in one last 32-hour burst during which, without sleeping a wink, he became the first person ever to traverse Antarctica from coast to coast solo, unsupported and unaided by wind.
