Ironman 70.3 Asunción 2027
IRONMAN 70.3 Asunción debuts on July 11, 2027 at the El Delta complex in Nueva Asunción (Chaco'i), about 5 minutes from the city center via the Héroes del Chaco bridge. It's a first edition: the official page still contains placeholder text, and final maps, cutoff times and logistics are missing. River swim (average water temp 19°C), bike and run listed as flat. July is winter in Paraguay: average highs of 22°C, lows of 11°C. The wind and speed ratings are conservative judgments due to lack of data; the times in the tables are rough estimates, not official data.

Three legs, three different races
Indicative profile · Scheda automatica da fonti pubbliche (2026-11): da rivedere. The organiser publishes the final course in spring: this page updates.
Swim1.9 km
- 1.9 km in the river, starting from the El Delta complex.
- Average water temp 19°C: wetsuit almost certainly allowed and recommended.
- Official communications mention a river with a favorable current, but it's placeholder text: check the final course map.
- The venue has already hosted a World Triathlon Cup, so the swim course is proven.
Bike90 km · — m D+
- 90 km labeled 'Flat' on the official page.
- No elevation data published: bring standard gearing anyway.
- The official blurb mentions climbs and mountain passes, but contradicts the 'flat' tag: it's placeholder text, not reliable until final maps are out.
- On a flat course, wind becomes the key variable: train to hold your aero position for long stretches.
Run21.1 km
- 21.1 km listed as flat on the official page.
- Promotional material hints at a pass through the city center, but that needs confirming with the final map.
- With highs around 22°C, running conditions should be favorable.
- First edition: no athlete race reports available, arrive with time to spare to scout the course on site.
