Athens Authentic Marathon Pacing Plan

The 284m of gain is concentrated into one long, sustained climb from roughly 10km to 31km, rather than being spread across rolling hills. This means you face over 20km of uphill running in the middle third of the race, including the grueling section at Agios Andreas near 15km, which is widely regarded as the toughest sustained uphill of any major marathon.

Given the flat opening 10km along the coast followed by a near-continuous climb to 31km, a positive split is effectively built into the course: you should bank controlled, relaxed pace early without over-pushing, since the climb will slow you regardless. Saving effort for the Agios Andreas grind around 15km is critical, as going out too hard on the flat coastal section will compound the damage on the long uphill that follows.

A true negative split is difficult here because the middle 20km climb will almost certainly be slower than the flat start, but the descent from 31km into Athens offers a chance to recover pace and finish strong. Many runners aim for an even-effort approach rather than even-pace, treating the descent as where lost time can partly be reclaimed before finishing in the Panathenaic Stadium.

Typical race-day conditions are around 13.7°C with wind near 11.1 km/h, which is relatively mild and shouldn't be a major limiting factor compared to the course's elevation profile. These conditions are manageable for sustained climbing effort during the 10-31km uphill stretch, though wind exposure could be a factor through the coastal section near Nea Makri.

The hardest section is the long climb through Rafina and Pikermi between 10km and 31km, with the steepest and most sustained grind occurring around Agios Andreas near the 15km mark. This over-20km uphill stretch is the defining challenge of the course, distinguishing it from flatter major marathons, and dictates how the entire race should be paced.
