In 2014, Nick Robinson, from South Africa, paddled 32km in the Guadiana River, from the town of Mertola (Alentejo, Portugal) to Alcoutim (Algarve, Portugal). The experience was exhilarating for him. He told new paddleboard friends about his adventure and they clamoured to go down again with him. Six months later the 2015 Guadiana Challenge took place with 18 of the top SUP racers in Portugal joining Nick. In 2016, 70 participants from 7 countries slogged down the river route and this year in 2017, between 100 and 150 paddlers from at least 8 countries are expected.
