“I’ve worked really hard to get to this point in my career," said Lucero.
But something that has helped motivate the 26-year-old weightlifter along the way is now missing -- her training journal.
"It has my workout numbers, random quotes and probably some tear drops along the way. It's a diary -- a personal piece of me. And it's gone," said Lucero.
Lucero kept her training journal in a bag with the rest of her gear. Christmas morning, Lucero discovered someone stole the bag out of her car while it was parked in front of her house.
"I had a bag they gave us to qualify for the World Championships. I had new shoes I had just broken in. I didn't think anyone would want that stuff," Lucero said.
The next day, a woman found some of Lucero's gear scattered on a nearby trail, saw Lucero's name on a piece of paper and contacted her through social media.
But the journal wasn't found.
One of Lucero's sponsors, QALO in Orange County, is now offering a $500 reward for Lucero's journal.
Lucero describes the journal as dark brown leather with a cross on the front and engraved with her name.
"I want it -- to be able to look at it later in life. When I'm struggling -- to remember what I went through when I was trying to make the Olympic team," said Lucero.
