Boston Marathon F50-54: Jenifer Martin Runs Away With It at the 128th

• Jenifer Martin (NJ) won the F50-54 group in 3:04:59 (7:03/mi), finishing more than 3 minutes ahead of runner-up Dyan Simon.
• Dyan Simon (WA) was the strongest climber in the field, moving from outside the top 900 among women at the start to 444th by the finish — and posted the 366th-fastest women's split on the 30K-to-20-mile stretch.
• Iris Klein (WA) closed hard, recording the 424th-fastest women's split from 25.2 miles to the finish to secure 3rd in 3:09:38.
• The top 20 in this 1,187-runner field were separated by just 13 minutes and 52 seconds, from Martin's 3:04:59 down to Kristin Johnson's 3:18:51 in 20th.

Jenifer Martin was never seriously threatened. She crossed Copley Square in 3:04:59 at a 7:03/mi clip — the kind of pace that commands respect on a point-to-point course that includes the Newton Hills and Heartbreak Hill. Her gender place among all women improved steadily from 421st at the first checkpoint to 300th by 20 miles, and she held that ground to the line, finishing 304th among women overall. The margin over second place — 3 minutes and 13 seconds — tells the story plainly.

Behind Martin, the race was a study in contrasts. Dyan Simon (WA, 3:08:12) was one of the great movers of the day, starting outside the top 900 among women and grinding her way up to 444th by the finish. She ran a 7:11/mi average and was especially strong through the 30K-to-20-mile segment. Iris Klein (WA, 3:09:38) took a different path, running a measured race and saving her best for last — her 25.2-miles-to-finish split was among the fastest in the women's field, and she edged past enough rivals to claim 3rd at 7:14/mi. Katsue Heginbotham (MA) rounded out the podium's near-miss in 4th at 3:10:56, while Sunita Singh (TX) was 5th in 3:12:25.

The cluster from 6th through 9th was remarkably tight: Agnieszka Rogut (ON, 3:12:46), Bernadette Versey (3:12:49), Chien-Li Lien (3:14:15), and Carolyn Smith (CO, 3:14:16) were separated by a total of just 90 seconds — with Versey and Smith each running 7:25/mi and finishing just one second apart. In a field of 1,187 finishers on one of the world's most demanding marathon courses, that kind of racing speaks for itself.
