Date: Sept. 28, 2025 Participant: Brice Kahler #11959 Race: 2025 Boulderthon Marathon Distance: 26.2 miles Weather: Perfect running weather with temperatures in the 50's to 70's and nice cloud cover

Early Control, Mid-Race Pop, Late Fade; 4:14:44 at 9:43/mi Finish: 4:14:44 (9:43/mi). 13-mile split: 1:58:56; last 13.2 miles: 2:15:48 (+16:52 vs first 13). Fastest miles: 12 in 8:37 and 10 in 8:42. First 10 miles averaged 9:08/mi; miles 11–20 averaged 9:37/mi; final 10K averaged 10:54/mi. Late-mile trend: 21–23 at 11:07/11:12/11:25, then 10:10 at mile 25. Action points: aim to shrink that +16:52 differential. Practice long runs finishing fast (last 6–8 miles near 9:20–9:30/mi). Add marathon-pace tempos (3–6 miles around 9:30/mi). In-race, cap early miles near 9:10–9:15/mi to preserve for miles 20–26 and target sub-10:30 splits there. Leverage proven pop—use controlled pickups like mile 12—after mile 18.
