Samantha Busch revealed the promise she made her late husband, NASCAR legend Kyle Busch, before his sudden death last month at age 41.

The mother of two, 40, shared a heartbreaking post to Instagram on Wednesday, June 10, that included photos of their children, son Brexton and daughter Lennix, back on the racetrack.

“Watching Brexton back at the track is both heartbreaking and beautiful all at once because there are moments when I catch a glimpse of Kyle in him, the same determination, the same passion, the same spark, and for a second it feels like a piece of him is still right here with us,” she began in the caption.

“These moments are incredibly hard, but they also remind me that Kyle’s story isn’t over,” she continued. “It lives on through the dreams he inspired and the two children he loved more than anything.”

Samantha revealed that she made her husband — who died after a severe case of pneumonia progressed into sepsis — a “promise” while he was “in the hospital.”

“I promised him that I would do everything I could to help our children pursue their dreams no matter what,” she said. “For Brexton, that dream is racing.”

Noting that this “wasn’t a dream Kyle chose for him,” Samantha said it was “something they shared.”

“Racing is what lights Brexton up and as long as it’s the dream in his heart, I’ll be right there beside him, cheering him on every step of the way,” she said. “And if one day his dreams take him somewhere else, that’s okay too. And if Lennix wants to get behind the wheel (we just bought her a kart for her 4th bday) it won’t be the same as having Kyle by her side but we will do our absolute best.”

Being back on the racetrack has been emotional for the family, she said.

“Every time we get to the track, we’re reminded that a piece of our team is missing,” she admitted. “The person who should be standing beside us isn’t there. That part is heartbreaking. But it’s also where we feel closest to him, surrounded by the memories, the people, and the dreams he helped build. So, we race on ❤️.”

Days before Kyle’s death, the highly accomplished racer celebrated his son’s 11th birthday, writing on Instagram, “You’re the best kid on & off the track, you amaze us every day. Keep doing what you’re doing and there is no limit to what you’ll accomplish! Love you buddy!”

In the days leading up to Busch’s shocking death, he continued to race despite being ill.
