When we were in China for World XC, Sonia O'Sullivan handed us a copy of her training log from March of 1998 - the month she won World Cross-Country (twice). With no major meets this weekend, now is the perfect time to learn what it took for O'Sullivan - who still is the Irish record holder at at every distance from 1k through the half marathon thanks to her 2:34.66 for 1,000, 3:58.85 for 1,500, 4:17.25 for the mile, 5:25.36 for 2,000 (still the WR), 8:21.64 for 3,000, 9:19.56 for 2 miles, 14:41.02 for 5,000, 30:47.59 for 10,000, and 67:19 for 13.1 PRs - to be the best in the world.
