The 32-year-old Mexican left his Los Angeles base last night to take a flight across the Atlantic in preparation for his September 7 challenge for Ricky Burns' WBO lightweight title and is expected to spend today settling into the new environs of his hotel in the city centre of Glasgow.
Beltran has his eyes open to a wealth of new experience, both sporting and cultural, on his first trip to these shores, but admits it is the education gained from his past that will be his true source of power when the first bell rings at the SECC a week on Saturday.
Eager to escape a grim existence poisoned by poverty, he travelled through the mountains to America from his native city of Los Mochis with his mother and siblings aged 15 and required more than one attempt to make it across the border as an illegal immigrant. He has worked in everything from shops to building sites to fruit farms to fast food restaurants and left his original base in Phoenix, Arizona, early in his boxing development to work with the late Emanuel Steward at the renowned Kronk Gym in Detroit.
Over the last nine years, though, it's as a preferred sparring partner for legendary eight-division world champion Manny Pacquiao at Freddie Roach's Wild Card Gym in Hollywood that Beltran has really completed his studies in the sweet science. First drafted in as a member of 'Team Pacquiao' ahead of the great man's first contest with Juan Manuel Marquez in 2004, he has developed a strong bond with the Filipino and will call upon his words of wisdom when it is Coatbridge's golden boy Burns who stands before him at the start of next month.
"Manny has really taught me how to be patient when the fight reaches a critical stage," said Beltran, who hopes victory in Glasgow will help him earn a Green Card. "If you get frustrated, you can be taken down by your opponent. Staying calm at the right times is vitally important and that's something he has taught me.
"Working with him has been a dream come true for me. It has been a struggle at times. I've earned my chance at this fight and I aim to make the most of it. I have been the underdog since I was born. I came from poverty, moved to the United States as an illegal immigrant and had to make my own way in boxing. Some fighters have people who bring them titles, but I never had a promoter until recently and had to put myself in this position through my own hard work."
That he ended up in Hollywood working with one of the greatest names in the game prior to earning his own crack at the world title is something the film industry in that part of the world might be well-advised to take a look at. "When I was a kid, I used to read newspaper stories about the great champions such as Julio Cesar Chavez and Sugar Ray Leonard and fantasise about what it would be like to meet them," recalled Beltran. "It has been wonderful to get the chance not just to meet one, but to spar with one.
"Knowing Manny has been such a privilege. For all that, I have served my time in boxing and I feel this is now my time to emerge as a world champion in my own right."
While far too respectful of Burns' abilities to indulge in trash talk, Beltran believes all the pressure is on the home fighter ahead of his fourth defence of the WBO crown. The Scot's management team are already talking of unification match-ups with Las Vegas-based promotions firm Top Rank keen to take him to New York's Madison Square Garden for a contest with American Terence Crawford.
Beltran insists Burns has to beat him comprehensively to make those match-ups happen, though, and feels that weight of expectation may take its toll. "There has been talk about Ricky coming to America to pursue his career," he said. "However, if he wants to go to the States, he has to really, really beat me and make people sit up and take notice. He has to be particularly convincing. That brings a pressure in itself, but I'm ready for this contest and I am going to make it hard for him."
Beltran has travelled to Scotland a week earlier than planned to negate the effects of jetlag and tiredness. He is keen to use some of his free time appreciating the natural beauty of the nation he has admired from afar and hopes he can develop a mutual respect with a fiercely partisan home crowd on fight night.
"I enjoyed the film 'Braveheart' but I'm aware of the mountains and the greenery and I hope to get the chance to see some of the scenery during my time there," said Beltran. "It looks really beautiful. People have been telling me it's cold, but I don't mind. I know about the history of the nation and I've seen photographs of a number of the old castles there. I want to make the very most of any time off I have between training. I really want to soak up the culture, meet the people and see what Scotland has to offer."
