I Became the Sprinting King After Running Away with the Baby

Zhang Po retired because of an injury, then spent two years miserable and despondent before accidentally falling into a river and drowning. When he opened his eyes again, he found himself in the body of a poor little wretch who had run away while pregnant and had just given birth. The original also had the name Zhang Po, the same looks, the same family circumstances, and the same relatives as him, but their lives had turned out completely differently. The other him, from a parallel timeline, had played a winning hand terribly. Just looking at it made him furious! For the first time in ages, his fighting spirit flared. He rolled up his sleeves and decided to get back in shape! Raising a child wasn't easy, so first he would reconnect with his estranged parents. Money was tight, so first he would win the prize money at the track and field street circuit. With a healthy body, his parents' support, and comfort from his angelic baby, Zhang Po returned to the starting line, his eyes fixed on the place he had once longed to reach. Later, the news of Zhang Po and his son Zhang Yi standing on the winners' podium caught everyone's attention. The child's other father rushed over with red eyes, but before he could say a word, Zhang Po, radiant with stardom and full of confidence, turned him down: "We don't know each other. If you want to see me, Mr. Zha, please make an appointment first." I'm terrible at writing blurbs, so this is all for now. The idea came to me after I saw a similar premise and wasn't satisfied. This is a self-indulgent work written to satisfy my own cravings. This isn't a romance-focused story. It follows the career and child-rearing plotlines, and the romance ends in tragedy. The love interest might barely appear at all. My ideas aren't fully developed yet, so the blurb may change at any time. Theme: Health! Exercise! Keep striving!
