Dangling from Lichu Sloan’s fingers, the oval medal depicts all the continents and oceans of the globe as backdrop to two silhouetted marathon runners. The words across the top read “Seven Continents,” and the word across the bottom says “Finisher.” Sloan isn’t finished. Not even close, although she did cancel a trip to run marathons in Korea, Saipan and Guam out of concern that she would be stuck in quarantine due to the coronavirus. She was supposed to have left on Thursday for that. She can’t bear the thought of being stuck. Instead, she’ll look forward to a marathon on the Cook Islands later this month, a return home to her husband, Paul, in Clifton Park, then a race in Kathmandu, Nepal, in April.
