Consistent Performance with Strong Initial Splits Mark maintained a steady pace throughout the marathon, starting strong with the first mile at 8:27 min/mile. This early pace positioned him 28th in his division. By mile 5, he climbed to 24th, showing early momentum. Mark's pacing varied slightly, with the fastest mile being mile 19 at 8:03 min/mile, indicating some energy reserve towards the latter part of the race. Despite fluctuations, he maintained a consistent pace around the 8:40 min/mile mark for a significant portion of the race. In the later miles, particularly from mile 22 onwards, there was a notable decrease in speed, with mile 25 being the slowest at 10:03 min/mile. Finishing with an overall time of 3:52:30 and an average pace of 8:52 min/mile, he placed 38th in his division. To improve, Mark might focus on maintaining a steady pace in the latter stages to sustain early race performance.
