The Dutchman broke free just as the original breakaway group was being reeled in, establishing an unassailable lead to claim his second victory at the race in three years.
Garmin-Sharp's Tyler Farrar came second in the 201km cobblestoned event with Astana's Borut Bozic third after a sprint to the line.
“Of course this race is on the Flemish roads with the small hills, the pave, and a lot of wind,” said Terpstra. “This race is suited for a guy like me.
"The attack on the Paterberg wasn’t planned, but in the final we know we have to be in front when we reach that point.
"I passed the front group on the Paterberg, I accelerated, and then I was alone. I knew the team was behind me to defend my attack. So, it gave me a lot of morale. I put myself in time trial mode and went to the finish.”
Once Terpstra made his move, a four-man chase group of Alejandro Valverde (Movistar), Stijn Devolder (Trek Factory Racing), Nicki Sorensen (Tinkoff-Saxo) and Terpstra’s team-mate Gert Steegmans followed, managing to cut the gap to seconds.
But they were unable to get any closer than that and the group were eventually caught, leaving Farrar and Bozic to battle it out for second.
“My heart is broken,” said Farrar. “This is the second time after 2011 that I won the group sprint in Waregem, just after the winner. I just wanted to win.”
