He woke up early every morning to go for long runs, followed a strict diet, and worked with a coach to improve his performance.<br>On the day of the race, Mark gave it his all and crossed the finish line with a personal best time, feeling proud of his accomplishment.
Can we infer that "Mark did not put in the effort to train for the marathon."? Yes, no, or maybe?
