F45-49 at CIM 2021: Bean Wrenn Runs Away With It

• Bean Wrenn, 48, clocked 2:47:54 (6:24/mi) — the fastest finish in the F45-49 field by more than eight minutes, putting her 1st among 417 finishers in the age group.
• A sub-2:58 top five: the first five finishers all broke 2:58, with just 10 minutes and 10 seconds separating Wrenn from 5th-place Janne Heinonen (2:58:04).
• Positions 2–5 were tightly bunched: Catherine Kruppa (2nd, 2:55:59), Sharon Lemberger (3rd, 2:56:53), Alexandra Lonergan (4th, 2:57:41), and Heinonen (5th, 2:58:04) were separated by a total of just 2 minutes and 5 seconds.
• A noticeable gap to 6th: Andrea Wilson (6th, 3:05:34) finished more than seven minutes back of Wrenn and over seven minutes behind the top five cluster.

On a mild Sacramento morning — 57°F, a light 4 mph breeze, broken clouds — the F45-49 age group delivered one of the day's most commanding individual performances. Bean Wrenn of Boulder, CO ran 2:47:54 at a 6:24/mi clip, a margin so decisive it rendered the rest of the field academic. She moved through the women's field steadily, sitting around 55th–57th among all women through the early miles before settling into the mid-60s by the finish — a reflection of the elite competition around her, not any fade on her part.

Behind Wrenn, a genuine four-way contest played out for the podium. Catherine Kruppa (2nd, 2:55:59, 6:43/mi) out of Houston posted the strongest first half among the chasers, logging the 121st-fastest women's split on the opening half. Sharon Lemberger (3rd, 2:56:53, 6:45/mi) of Menlo Park was the 97th-fastest woman on the 5K–15K stretch but faded through the back half, sliding from 98th among women at 5K all the way to 137th by the finish. Alexandra Lonergan (4th, 2:57:41, 6:47/mi) actually moved the other direction — from 158th among women early to 145th at the line — showing a composed, negative-split-style approach. Janne Heinonen (5th, 2:58:04, 6:47/mi) mirrored that progression, climbing from 167th to 153rd among women and posting her best relative split on the 30K–40K segment.

After that top-five burst, the field spread out considerably. Andrea Wilson (6th, 3:05:34) and Fumie Weiby (7th, 3:05:56) finished within 22 seconds of each other at 7:05/mi, while Carla McAlister (8th, 3:07:46), Karen Frindell Teuscher (9th, 3:09:20), and Jessica Hofheimer (10th, 3:09:36) rounded out a tight 8th-through-10th cluster. All told, 417 women raced F45-49 at CIM 2021 — a deep field on a fast course, crowned by a dominant performance from Wrenn that will be hard to forget.
