Find your marathon. Pace the real course.

Even-effort pacing holds a steady physiological effort rather than a steady pace, so you run a little slower up the climbs and a little faster down the descents. On a course with real hills it is usually faster overall than even splits, and it leaves you fresher in the closing kilometres.

We cover the seven Abbott World Marathon Majors (Tokyo, Boston, London, Berlin, Chicago, New York and Sydney), the biggest marathons across Australia and New Zealand, and a growing set of international races like Valencia, Paris, Amsterdam and Cape Town. Every course on this page has its own course-aware pacer with an elevation profile and splits. Some run on official routes; the rest use community-sourced traces, which we mark clearly and switch to the official route as we build each one.

Splits are distributed by the energy cost of each gradient using the Minetti (2002) running-economy model, the canonical metabolic-cost-of-grade curve, with a deliberate cap on the downhill benefit so the plan protects your quads. Elevation is sampled from the SRTM 30 m model along each official route and checked against the organisers' published figures. Treat it as a close guide, good to about ±10–15 s/km, not a surveyed plan.
