Ingrid Kristiansen

A former cross-country skier, Kristiansen became the only athlete to hold the world records at 5,000m, 10,000m and the marathon at the same time. Her 2:21:06 in London in 1985 stood for 13 years, and she won London four times plus Boston twice and New York once. She is the range story on this list: equally at home winning a world track title in 1987 and grinding out a solo record on the roads.
