F30-34 at CIM 2021: Liza Howard Runs Away with It

• Liza Howard wins the F30-34 age group in 2:37:34 (6:01/mi) — nearly five minutes clear of 2nd place.
• Sarah Jackson (2nd, 2:42:27) and Lauren Ames (3rd, 2:43:47) both ran strong second halves — Jackson's was the 25th-fastest among all women on the back half, Ames's the 34th-fastest.
• Natalie Chirgwin stormed from 70th among women at the start to 41st by the finish, posting the 19th-fastest women's split on the 30K–40K stretch.
• Gracia Sich (5th, 2:47:19) and Emily Rybak (6th, 2:47:33) finished just 14 seconds apart, with Nicole O'Loughlin (7th, 2:47:56) only 23 seconds further back — three athletes separated by under 40 seconds in a 519-woman field.

In a field of 519 F30-34 finishers on a crisp Sacramento morning — 57°F, light wind, near-ideal conditions — Liza Howard made it look almost easy. The 33-year-old from Toronto crossed in 2:37:34 at 6:01 per mile, a margin of 4:53 over runner-up Sarah Jackson. Howard sat 18th among all women at the 5K mark and steadily climbed, cracking the top 15 by the halfway point and finishing 13th among women at 40K before settling 14th at the line. Her 15K-to-half split ranked 14th-fastest among all women in the race — a sign she was doing her best work in the middle miles while others were still finding their legs.

Jackson (2:42:27, 6:12/mi) and Lauren Ames (2:43:47, 6:15/mi) both made their moves in the back half. Jackson advanced from 41st among women at the start to 29th by the finish, her second half ranking 25th among all women. Ames was even more aggressive off the gun — she was 54th among women early and clawed all the way to 36th, her second-half split ranking 34th in the women's field. The two traded positions for much of the race before Jackson pulled 80 seconds clear at the tape.

The most dramatic charge of the day belonged to Natalie Chirgwin (4th, 2:45:19). She was buried — 70th among women and even sliding back slightly to 72nd by 15K — before an explosive 30K-to-40K segment that ranked 19th among all women launched her into the top 50 and eventually to 4th in the age group. Gracia Sich (5th, 2:47:19) told the opposite story: she rolled through the early miles as high as 36th among women but faded to 58th by 30K and held there, still finishing a respectable 5th. Behind her, Rybak (6th, 2:47:33), O'Loughlin (7th, 2:47:56), Anna Dulko (8th, 2:48:27), Keelyn Van Breda (9th, 2:48:27), and Emma Grimes (10th, 2:48:36) completed one of the tightest top-ten closings in the age group — five athletes within 69 seconds of each other.
