In the years since, he’s proven to be the most consistent rider in PBR history.
He was the first rider to reach 600 qualified rides at the elite televised level and in addition to his lone world title, he’s now finished second in the world a remarkable five times.
"It was my perseverance to never give up, to believe in my ability and on my goals that I wanted to achieve,” Marchi told Rafael Vilella during recent interview in Brazil.
Now in his 14th year as a pro in the PBR, the 35-year-old Monster Energy bull rider is currently ranked 22nd in the world standings and on the verge of qualifying for an unprecedented 14th consecutive World Finals in Las Vegas.
All this despite naysayers believing that Marchi has been on the verge of retirement for years.
Yet one season after another he’s proved them all wrong.
This past weekend, Marchi split second in the 15/15 Bucking Battle on CBS with an 87.75-point effort on Uncle Tink. Since the beginning of March, only once has he gone an entire elite PBR event without at least one qualified ride and only once has he bucked off of as many as four bulls in a row.
He’s finished in the Top 5 three times this year, including a three-week stretch where he finished third in Jacksonville, Florida, and fourth in Albuquerque, New Mexico.
And since the stretch run commenced in Tulsa, he’s recorded a pair of Top 10 finishes in the past three events.
"Perseverance is what Guilherme has to tell us today,” Vilella said. “If you get close to your goal, but didn't achieve it, keep trying (and) don't give up.”
Marchi has ridden in an astonishing 361 events at the elite televised level in the PBR.
With eight more events this year, including the World Finals, he can run that total up to 369 events by year’s end, leaving him with a viable shot at actually earning another historical achievement—becoming the first PBR rider to nod his head in 400 events at the elite televised level of competition.
It isn’t that Marchi is merely competing for so many years that has led to these accomplishments.
It’s that he’s been so damn consistent and, as he told Vilella, “Never give up.”
Those words are simply not in his vocabulary.
And, if they were, giving up is not something that even occurs to Champions like him.
