Twin Cities Marathon 3:45 pace chart
A 3:45:00 finish at the Twin Cities Marathon averages 8:35 per mile (5:20 per kilometre) — a fast recreational time, roughly the top quintile of a big-city field. Run at even effort rather than even pace, the easiest mile comes in around 7:57/mi and the hardest around 9:20/mi — about 82 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 1:52:03 — a 0:53 positive split, which is what the terrain costs you rather than a pacing error. The hardest mile on the course sits near kilometre 2; at this goal time it should take 9:12/mi, and giving it that time is the difference between finishing Minneapolis on plan and unravelling in the last hour.
Mile-by-mile targets for 3:45:00
Grade-adjusted splits computed from the Twin Cities Marathon elevation profile with the Minetti gradient-cost model, scaled so the full course adds up to 3:45:00. Uphill sections get more time, downhills less, at one constant effort throughout.

Frequently asked questions
What pace is a 3:45 marathon?
A 3:45:00 marathon is 8:35 per mile or 5:20 per kilometre held for the full 26.2 miles (42.195 km). On the Twin Cities 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 3:45 at the Twin Cities Marathon?
1:52:03. That is the grade-adjusted halfway target for this course, not simply half of 3:45:00 — 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 Twin Cities Marathon?
Even effort at a 3:45 goal produces splits between 7:57 and 9:20 per mile — about 82 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 Twin Cities 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 3:45:00. Uphill sections get more time and downhill sections less, at a constant effort throughout.
Is 3:45 a realistic marathon goal?
3:45 is a fast recreational time, roughly the top quintile of a 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.
