On the third floor of the Montreal Chest Institute, at McGill University, Olga Kotelko stood before a treadmill in the center of a stuffy room that was filling up with people who had come just for her. They were there to run physical tests, or to extract blood from her earlobe, or just to observe and take notes. Kotelko removed her glasses. She wore white New Balance sneakers and black running tights, and over her silver hair, a plastic crown that held in place a breathing tube.
Tanja Taivassalo, a 40-year-old muscle physiologist, adjusted the fit of Kotelko’s stretch-vest. It was wired with electrodes to measure changes in cardiac output — a gauge of the power of her heart. Taivassalo first met Kotelko at last year’s world outdoor masters track championships in Lahti, Finland, the pinnacle of the competitive season for older tracksters. Taivassalo went to watch her dad compete in the marathon. But she could hardly fail to notice the 91-year-old Canadian, bespandexed and elfin, who was knocking off world record after world record.
Masters competitions usually begin at 35 years, and include many in their 60s, 70s and 80s (and a few, like Kotelko, in their 90s, and one or two over 100). Of the thousands who descended on Lahti, hundreds were older than 75. And the one getting all the attention was Kotelko. She is considered one of the world’s greatest athletes, holding 23 world records, 17 in her current age category, 90 to 95.
