Course
The Patagonian International Marathon course
Every distance is point-to-point on the winding gravel and asphalt roads southwest of Torres del Paine National Park, finishing at the Hotel del Paine in the Serrano sector, with official buses from Puerto Natales to the starts and back. The 42K starts at Lago Maravilla on Route Y-200 at 9:30 a.m. on Saturday, the 21K at Cipreses (Route Y-290, km 47) at 10:30 a.m. and the 10K at Cuernos del Paine at 9:30 a.m., while the 30K (Lago Porteño) and 15K (Lago Toro) run on Sunday.
Read the full course notes
On the published profile, the marathon's first half to Cipreses stays low and gently rolling between about 40 and 80 m, then the course turns hilly: after Lago Toro it climbs to the high point of 257 m around km 30 before descending past Cuernos del Paine and rolling to the finish. The marathon totals 687 m of climbing and 718 m of descent, about 74% of it on gravel, and the shorter races mix gravel and asphalt more evenly. Aid stations sit roughly every 5 km, the marathon has a 13:00 cutoff at Cipreses, and all finishers must be in by 16:30 (7 hours for the 42K).

- Weather on race day
- Early September is late winter in Patagonia, and the organisers report average temperatures of 2–10 °C, occasionally reaching 15 °C. The race falls outside the season of strong, persistent winds, but a storm is always possible, so pack layers, gloves and a windproof jacket and dress for changing conditions rather than the forecast.
What to train for
This is a strength race: build long runs on unpaved roads or trails with rolling terrain, and for the marathon reach 30–32 km including a sustained climb in the last third, since the biggest hill arrives around km 27 to 30.
Run 6–8 × 3 minutes uphill at threshold effort weekly, and practise descending relaxed on loose gravel so your quads survive the drops after the high point.
Train by effort and time rather than pace, as gravel, wind and cold all slow the clock. Do a few runs in cold, windy weather wearing the layers you plan to race in, and practise eating with gloves on.

- Goal-pace run, 16 km with 10 km at race pace
- Friday
- Recovery run, 6 km, or cross-train

Your build to race day
Taper
Tapering for the Patagonian International Marathon
Start the taper two to three weeks before race day. Cut your weekly volume by about a third, then by half in race week, and keep a few short efforts at race pace so your legs stay sharp. The course rolls, so keep one short session on undulating ground in the first taper week. With the race on September 4, 2027, your taper starts around August 17, 2027.

How long should I train for the Patagonian International Marathon?

Rolling. Every distance is point-to-point on the winding gravel and asphalt roads southwest of Torres del Paine National Park, finishing at the Hotel del Paine in the Serrano sector, with official buses from Puerto Natales to the starts and back.
