Date: Sept. 28, 2025 Participant: Odelia Drillich #11433 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

Fast start, four-hour finish, and a resilient close 4:00:16 (9:10/mi). Early speed: 9 of first 12 miles sub-7:40; fastest 7:17 (mile 2). Splits: 6 mi 44:57, 10 mi 1:15:54, 13 mi 1:39:32, 20 mi 2:43:38. Final 13.2 in 2:20:44; miles 20-24 at 11:38, 13:22, 12:09, 14:00, 14:08; rally to 11:10 and 9:56 for miles 25-26. Coaching notes: marathon pace improved vs prior half (10:17/mi in 2:14:53) to 9:10/mi over double the distance. To translate early speed into steadier outcomes, open near intended pace, cap early miles within ~20-30 sec/mi of goal through 16, and emphasize even-split long runs (marathon-pace blocks, fast-finish). Use 10-20-mile checkpoints to hold effort, then build gradually over the last 10K.
