Strong Start, Challenging Finish Rosa began her race with a controlled pace, clocking her first mile in 11:03 min/mile. Notably, her second split was a swift 9:57 min/mile, indicating a strong start. Her pace was relatively steady through various segments, achieving a series of sub-10:30 min/mile splits, particularly excelling between miles 8 through 10 with consistent improvement. A steep drop in performance was observed at mile 13, where the split time dramatically increased to 1:49:14, vastly impacting her overall pace, concluding with an average of 19:07 min/mile. This shift saw her positioning move from the 2698th overall at mile 12 to 5273rd at the finish. Focusing on endurance in the final miles could be beneficial. Training on sustaining speed as fatigue sets in might yield positive results in future races. Your ability to pick up the pace earlier in the run indicates potential for improvement in that final stretch.
