AceShowbiz - Joe Amabile, a former contestant on "Bachelor in Paradise," has announced that he will not be participating in the TCS New York City Marathon due to a fever and back pain.

Amabile took to Instagram on Sunday morning, November 3 to share the news, stating that he woke up with a temperature over 100 degrees and aches all over his body. "After the shakeout run yesterday, my back was aching and I caught a fever," he wrote. "I was really hoping it was going to break through the night."

Despite his disappointment, Amabile acknowledged that it was not safe for him to run the 26-mile race. "Probably best that I don't run 26 miles today," he said.

Amabile's fellow "Bachelor Nation" alumni shared their support in the comments section, wishing him a speedy recovery. Kaitlyn Bristowe wrote, "Shooooot I'm so sorry," while Matt James added, "Ahh man sorry to hear that, rest up Joe!"

Amabile's wife, Serena Pitt, revealed in an Instagram Story on Saturday that her husband was exhausted from his illness. "IDK how this man plans to run a marathon tomorrow," she wrote, sharing a photo of him bedridden.

While Amabile recovers, he will be cheering on his fellow "Bachelor" and "Bachelorette" alums running on Sunday, including Tayshia Adams and Peter Weber. Despite the setback, Amabile remains optimistic about his future running endeavors.
