Costa managed the feat when he ended third in the Men’s H5 23.3 km time trial. Former Formula One driver Alessandro Zanardi, the man who motivated Luís to take up the sport, won the gold medal.
He followed this up by ending fourth in a 60.7km individual road race, despite recording the same time as the eventual winner.
His previous best result at the World Championships was 7th along with an 8th position at the Olympics.
In comments to The Portugal News shortly after his ground-breaking achievement for the sport in Portugal, Luís Costa said: “I entered this time-trial with some anger as I have had a lot of misfortune this past week.
“I fell on Tuesday and I could only replace the damaged parts on Wednesday afternoon. This caused me considerable stress, but also made me want to show even more that I was here to fight for a podium finish.
“I started strongly and carried on through to the end, evidence of which is the fact that I finished only 47 seconds behind the race winner Alessandro Zanardi.
“I’m super happy and I hope this medal brings me more recognition from potential sponsors in the future”, Luís concluded.
