Consistent Splits With a Slight Slowing Towards the End Oscar Sarabia maintained impressive pacing at the 2025 Boulderthon Half Marathon, with early splits showing steady acceleration from 7:54 to 7:31 min/mile by mile 7. His ability to gradually improve his place from 533rd to 342nd by mile 9 highlighted his efficient pacing strategy. Notably, Oscar reached the peak of his performance mid-race, securing his best split with a time of 7:31 min/mile. However, some deceleration occurred in the latter stages, increasing his overall elapsed pace to 7:45 min/mile. The split times of 8:38 by mile 11 and consistent 8:03 from mile 12 onwards indicated fatigue might have influenced his final position of 419th overall. Focusing on endurance towards the end could optimize future performances. Despite this, Oscar's progress through the field and consistent early pacing is commendable.
