Cómo inscribirse en el Maratón de Santiago

Entry fees, closing dates and start times are set by the organiser and change every year, so they are not reproduced here — a stale deadline is worse than none. The organiser’s own site and its social channels are the authoritative source for the current year, and are where entry opens.

Cómo prepararse para el Maratón de Santiago

How long to train

Build for 16 to 20 weeks from a base you already hold rather than from nothing. For marathon the block should peak at a longest run of 30–32 km, reached at least two weeks before race day so there is time to taper. Three weeks of taper is standard: cut volume by roughly a third each week while keeping some race-pace work so the legs stay sharp.

Training for this course

The course mixes surfaces and gradients, so build a training block that does the same rather than repeating one flat loop. Vary where you run week to week so nothing on race day is unfamiliar.

Conditions in April

Conditions are usually good for racing: highs average 23.3°C and lows 11.8°C in April, which is close to ideal for marathon running. Dress for the temperature about ten degrees warmer than it actually is, since you will warm up within two kilometres.

Fuelling

Over 42 km you will need 30–60 g of carbohydrate an hour from early on, not once you feel empty. Rehearse the exact products in training — the gut trains like anything else — and check in advance which brand is handed out on course, because switching to an unfamiliar one mid-race is a common and avoidable mistake.

Race week

Sleep matters most two nights before, not the night before, so protect that one. Keep eating normally with a modest tilt toward carbohydrate, lay out kit the night before, and do nothing new: no new shoes, no new breakfast, no new socks. Plan to arrive at the start with time to spare — marathon fields move slowly through bag drop and security.
