Strong Opening Miles Give Way to a Tougher Back Half Cristina Bruzual finished the marathon in 4:36:34, compared with 4:29:07 at the same event last year. Her early splits were the highlight: miles 1 through 11 clicked off in the 9:029:29 range, holding a cumulative pace near 9:17/mile through the halfway point. From mile 12 onward, per-mile times eased into the 10:0010:37 range, then dipped further between miles 19 and 23, before firming back up over the final three miles to close in the 10:2912:54 range. That mile 1923 stretch overlaps with the courses lululemon Power-Up Zone, set at roughly mile 22.5 of the marathon a useful landmark to lean on next time to help sustain the rhythm she carried through the first half. Given the elevation of Boulder at over a mile high, holding that early pace as long as she did was a solid building block for future races here.
