Consistent Performance with a Strong Finish Claire Blanken completed the 2025 Boulderthon Half Marathon with an overall time of 2:16:03, achieving an average pace of 10:23 min/mile. Notably, she secured 271st place in her division F30-34 out of 654 participants. Throughout the race, Claire's splits featured a significant improvement. A highlight was her performance in the second half, notably reducing her split time to 9:07 min/mile at the 12th mile, showing a decrease in pace after the initial slower miles. Claire's race strategy appears to have been well-planned and executed based on her precise pacing adjustments. Her transition from a 15:29 min/mile in mile 4 to consistently faster paces by mile 5 and beyond suggests that she managed her energy reserves efficiently. Maintaining a steady pace and progressively accelerating towards the end indicates room to build on already solid improvements. Emphasis on consistent pacing in earlier miles could further enhance her race tactics in the future.
