Philadelphia Marathon 4:15 pace chart

A 4:15:00 finish at the Philadelphia Marathon averages 9:44 per mile (6:03 per kilometre) — the classic sub-4 target, close to the middle of a typical big-city field. Run at even effort rather than even pace, the easiest mile comes in around 8:56/mi and the hardest around 10:38/mi — about 103 seconds between the two extremes. Holding an identical number on every mile of a course with this profile means running the climbs too hard and the descents too easy. Held at even effort, halfway comes up at 2:08:10 — a 1:19 negative split, because the harder half comes first. The hardest mile on the course sits near kilometre 15; at this goal time it should take 10:31/mi, and giving it that time is the difference between finishing Philadelphia on plan and unravelling in the last hour.

Mile-by-mile targets for 4:15:00

Grade-adjusted splits computed from the Philadelphia Marathon elevation profile with the Minetti gradient-cost model, scaled so the full course adds up to 4:15:00. Uphill sections get more time, downhills less, at one constant effort throughout.

Frequently asked questions

What pace is a 4:15 marathon?

A 4:15:00 marathon is 9:44 per mile or 6:03 per kilometre held for the full 26.2 miles (42.195 km). On the Philadelphia Marathon specifically, the elevation profile means even effort produces uneven splits — the table on this page gives the target for every mile.

What should my halfway split be for a 4:15 at the Philadelphia Marathon?

2:08:10. That is the grade-adjusted halfway target for this course, not simply half of 4:15:00 — it accounts for where the climbing sits. Reaching the half meaningfully faster than this on this course usually means you have spent the effort you need for the closing miles.

Should I run even splits at the Philadelphia Marathon?

Even effort at a 4:15 goal produces splits between 8:56 and 10:38 per mile — about 103 seconds between the easiest and hardest one. Grade-adjusted pacing gives back time on the descents and spends it on the climbs, which is what running an even physiological effort actually looks like on a course with this profile.

How are these Philadelphia Marathon splits calculated?

Each mile is weighted by its gradient using the Minetti et al. (2002) cost-of-running polynomial, which measures the metabolic cost of running at grades from −45% to +45%. The total is then scaled so the whole course adds up to 4:15:00. Uphill sections get more time and downhill sections less, at a constant effort throughout.

Is 4:15 a realistic marathon goal?

4:15 is the classic sub-4 target, close to the middle of a typical big-city field. Whether it is realistic for you depends on your recent race results and weekly volume rather than on the number itself — the race-time predictor on this site will convert a recent 5K, 10K or half-marathon result into a marathon estimate using the Riegel power-law model.
