Trail Running Ecuador

Before you run here

Four short guides with their sources. Checked October 5, 2026.

Altitude and acclimatization

  • Quito and Cuenca are above 2,500 m, and several highland races go above 4,000 m. Altitude sickness can start from about 2,450 m.
  • If you are coming from the coast or from abroad, arrive early: two or three nights at the height of Quito or Cuenca before going higher protect you a lot.
  • For the first two days, keep exercise light and skip alcohol.
  • A headache with nausea, dizziness or unusual tiredness is altitude sickness. Don't go higher while it lasts.
  • Shortness of breath at rest, confusion or stumbling are an emergency: go down at once and call 911.
  • If you are thinking of taking medication to prevent it, ask a doctor first.

Mandatory kit

  • Each race publishes its list in the rules or the runner's guide. Read it before you sign up: there is usually a kit check, and runners without the kit can be disqualified.
  • Mountain races almost always ask for a waterproof jacket, a space blanket, a whistle, a headlamp, a charged phone, and water (often 1 to 2 litres) with some food.
  • At altitude the weather changes fast. Some races switch on a cold-weather kit (hat, arm or leg cover, jacket) or a hot-weather kit (more water) a few hours before the start, announced by email and social media.
  • Save the organizers' emergency number in your phone and download the map before you go: there isn't always signal on the páramo.

Rainy seasons by region

  • Highlands: two rainy seasons, February to May and October to November.
  • Coast: the rainy season runs from December to May.
  • Amazon: it rains all year; the wettest months are March to May and October, the driest August and September.
  • In the rain, páramo and forest trails turn to mud and rivers rise. Check whether the race has a bad-weather route, and wear shoes with good grip.
  • 2026–2027: El Niño is strengthening. In September 2026 the ERFEN committee warned that the last quarter of the year will decide whether the coast and Galápagos get above-normal rain.
  • For the forecast on race days, check INAMHI.

ITRA points and the UTMB Index

  • Both systems measure effort in km-effort: each kilometre counts 1 and each 100 m of climb adds 1 more. A 45 km race with 1,500 m of climb is 60 km-effort.
  • ITRA points (0 to 6): earned by finishing an ITRA-evaluated race, according to its effort. They count once the organizer uploads the results; you only need an ITRA account (membership isn't required).
  • UTMB Index: UTMB's own index, separate from ITRA's, in four categories: 20K, 50K, 100K and 100M. It becomes active when you finish a UTMB Index or UTMB World Series race in that category within the last 24 months.
  • Running Stones are entries in the draw for the finals in Chamonix (UTMB, CCC and OCC). You earn them at by UTMB races such as Quito Trail by UTMB: 1 for a 20K, 2 for a 50K, 3 for a 100K and 4 for a 100M. To enter the draw you need at least one from the last two years and a valid UTMB Index in the category.
  • The races in Ecuador that count for the UTMB Index are in the calendar. See UTMB Index races
