The 88 km (54.6 miles) Maratón Internacional Hernandarias – Paraná is held in Argentina.

Erica Rose, who completed the downstream swim in Paraná River in 9 hours 40 minutes in 2007 and 10 hours 5 minutes in 2005 recalls her experience, “The race itself is incredible. It is challenging, for sure.

There are some points when the river is narrow and you feel like you’re moving quickly, but there are other points where you can’t see either bank of the river at all and you have no idea where you are or if your rowers are taking you in the right direction.”
