Beating Yourself : How Do Runners Improve Their Own Records?

Pacing studies suggest the distribution of effort for optimizing performance. Cross- sectional studies of 1-mile world records (WR) suggest WR progression includes a smaller coefficient of variation of velocity (CV). Purpose: This study evaluates whether intra- individual pacing used by elite runners to break their own WR (1-mile, 5-km, 10-km) is related to the evolution of pacing strategy. We provide supportive data from analysis in sub- elite runners. Methods: Men’s WR performances (with 400-m or 1-km splits) in 1-mile, 5-km and 10-km were retrieved from the IAAF database (1924- present). Data were analyzed relative to pacing pattern when a runner improved their own WR. Similar analyses are presented for 10-km performance in sub-elite runners before and after intensified training. Results: WR performance improved in 1-mile (3:59.4±11.2 to 3:57.2±8.6), 5-km (13:27±0:33 to 13:21±0:33) and 10-km (28:35±1:27 to 28:21±1:21). The average CV did not change in the 1-mile (3.4±1.8 to 3.6±1.6%), 5-km (2.4±0.9 to 2.2±0.8 %) or 10-km (1.4±0.1 to 1.5±0.6%) with improved WR. When velocity was normalized to the % mean velocity for each race, the pacing pattern was almost identical. Very similar patterns were observed in the sub-elite runners in the 10-km. Time improved from 49:20±5:30 to 45:56±4:58, normalized velocity was similar, terminal RPE increased (8.4±1.6 to 9.1±0.8), CV was unchanged (4.4±1.1 to 4.8±2.1%), and VO2max increased (49.8±7.4 to 55.3±8.8 ml.min-1.kg-1). Conclusion: The results suggest that when runners break their own best performances, they employ the same pacing pattern, which is different from when WR are improved in cross- sectional data.
