Why people love it

  • Waterfront Costanera course with start, transitions and finish in one area
  • Mostly flat bike, two 90 km (56 mi) loops
  • Average water about 20 °C (68 °F), in the comfortable range
  • Young race (2025 debut) with strong local and sponsor backing

Watch out for

  • No athlete reviews yet, so every rating is provisional
  • Heat risk: October highs reached 34 °C (93 °F) in 2025
  • Remote border city, about 370 km (230 mi) from Asunción by road
  • Elevation and run profile are unpublished, and sources conflict on flat versus hilly
