The purposes of this study were to describe variability of pacing during a marathon and to determine if there is a relationship between variability of pacing and marathon performance. A total of 301 race profiles that contained personal global positioning system (GPS) from the Rock „n‟ Roll Las Vegas (Race 1) and San Diego (Race 2) marathons were downloaded (http://connect.garmin.com) and analyzed. Each marathon finish time was placed into one of three finish time bins: Bin 1: 2.5 – 3.9 hrs, Bin 2: 4.0 – 4.6 hrs, Bin 3: 4.7 – 7.2. The coefficient of variation of velocity (Velcov) was calculated for each race profile and compared between races using an independent T-test. Velcov was not different between races (Race 1: 16.6 ± 6.3%, Race 2: 16.7 ± 6.5%). Velcov was lower in Bin 1 vs. Bin 2 (p < 0.05), lower in Bin 1 vs. Bin 3 (p < 0.05), and lower in Bin 2 vs. Bin 3 (p < 0.05) for both races. It was determined that Velcov was different between marathon finish times such that Velcov was greater for slower finish times for either race. It appears that slower marathon finishers had greater Velcov compared to faster marathoner finishers. These results indicate it would be prudent to match training specificity with the event and runner ability.
