Fifth straight New York, first sub-3:30, in 3:26:21

An r/Marathon_Training poster ran 3:26:21 at the New York City Marathon on November 1, breaking 3:30 at their fifth consecutive attempt at the race.

The build was not huge. About 45 miles a week on average, a 53 mile peak, and a longest run of 21 miles three weeks out. The A goal was 3:25 and the B goal was sub 3:30. They ran with the 3:25 pacer for the first nine miles, decided the group was going too fast, and let it go rather than chase.

The fueling change

The one thing that was new this year was the eating. The poster carb loaded for three days, as much as they could tolerate, which they say they had never done in their four previous New Yorks. On the course they took 50g of carbs and 450mg of sodium every four miles, drank water at most aid stations, and grabbed mini bottles from spectators so they could skip a few.

The result, in their words, was a race without the usual late collapse. They say they felt strong for most of it despite weather a bit warmer than they wanted, with no cramps and no wall.

The splits

The mile chart is the proof. After a 7:58 opener, almost every mile sits between 7:40 and 7:56. The two slow ones are mile 15 at 8:28 and mile 16 at 9:35, and then it goes straight back to 7:48 and holds. Mile 26 is a 7:10, which the poster describes as sending it over the last stretch. They added in an edit that they had not realised how even the pacing was, with the second half only 39 seconds off.

By mile 20 the maths was already done. The poster writes that they could have run the last six miles at nine minute pace and still gone under 3:30, and that at that point they knew it was in the bag.

What it actually means

This is one runner's race report, not a study, and plenty changed between year four and year five that nobody can separate out. But it is a useful shape for anyone grinding at the same course. Mileage stayed modest, the long run topped out at 21, and the thing the runner himself credits is the fuel, three days of carbs before and a steady 50g every four miles on the day. Five tries at the same race also counts for something. The breakthrough came on the course they know best.
