Consistent Effort with Notable Progress Ariel Shlosberg delivered a solid performance at the 2025 Boulderthon Marathon. Ariel displayed consistent pacing across most of the race, maintaining an average pace close to 9:03 min/mile for the first 10 miles. The fastest mile was the final one, clocking in at 8:37 min/mile. The early positive splits reflect initial strength and energy, but there's a noticeable slowdown from mile 20 onwards, with the pace dropping to 11:25 min/mile at mile 20. Despite the late-race slowdown, Ariel improved significantly from their previous marathon in 2023 by cutting total race time down by over 20 minutes. Maintaining a better average pace of 9:46 min/mile compared to the previous 10:40 min/mile suggests an improved endurance level and race strategy. Focusing on sustaining pace in the latter part of the race could yield even better results in the future. Overall, this performance highlights a strong progression and a promising trajectory for future races.
