Strong Start, Steady Fade, Late Rally Madeline Porior-Arce finished the marathon in 4:13:38. Her first half came through in 1:57:47, holding a pace in the 9:009:15 range through mile 13. Miles 6 through 11 were her strongest stretch, averaging close to 8:55 per mile, including a fastest split of 8:24 in mile 6. The second half slowed gradually, dipping into the 10:0011:12 range between miles 18 and 22, before firming up over the final miles to close in 9:50. The slower stretch around mile 22 came near the lululemon Power-Up Zone, roughly mile 22.5 on the marathon course. Running at Boulder's altitude of over 5,000 feet, Porior-Arce's ability to hold sub-10:00 pace through the first two-thirds of the race set up a finish that trimmed only slightly off her elapsed pace by the close.
