Chicago Marathon 6:00 pace chart

A 6:00:00 finish at the Chicago Marathon averages 13:44 per mile (8:32 per kilometre) — a steady, sustainable finish, and the pace most first-time marathoners should actually target. Run at even effort rather than even pace, the easiest mile comes in around 13:31/mi and the hardest around 13:53/mi — about 22 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 2:59:48 — an almost exactly even split. The hardest mile on the course sits near kilometre 28; at this goal time it should take 13:46/mi, and giving it that time is the difference between finishing Chicago on plan and unravelling in the last hour.

Mile-by-mile targets for 6:00:00

Grade-adjusted splits computed from the Chicago Marathon elevation profile with the Minetti gradient-cost model, scaled so the full course adds up to 6:00:00. Uphill sections get more time, downhills less, at one constant effort throughout.

Frequently asked questions

What pace is a 6:00 marathon?

A 6:00:00 marathon is 13:44 per mile or 8:32 per kilometre held for the full 26.2 miles (42.195 km). On the Chicago 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 6:00 at the Chicago Marathon?

2:59:48. That is the grade-adjusted halfway target for this course, not simply half of 6:00:00 — 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 Chicago Marathon?

Even effort at a 6:00 goal produces splits between 13:31 and 13:53 per mile — about 22 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 Chicago 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 6:00:00. Uphill sections get more time and downhill sections less, at a constant effort throughout.

Is 6:00 a realistic marathon goal?

6:00 is a steady, sustainable finish, and the pace most first-time marathoners should actually target. 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.
