Almost lost my life

It was spectacular moment that I wasn't prepared to face. I came into contest with other runners in a 65-kilo run around Hong Kong Island yesterday. The run started at 6am in the morning. It took me 9 hours to complete it. Although it was cool at first but heat start swelling up. By the time it reaches 12 noon. the heat was unbearable and my body was overcome by heat, start feeling chill up to my spine, at which time I knew I might have suffered a heat stroke. I slowed and stayed motionless for 15 minutes under the shade and saw all runner passed me by. At that time I completed only 45 kilometers with 20 to go. With determination that I wasn't prepared to give up by entered into the race as a senior age over 50, I intended to complete it regardless of time. I continued working on my pace and started regain some of lost energy. Timing on my first leg which was 3 hours for the first 35 kilometers was a lot faster than my second leg which took me almost 6 hours to complete. It's a horrific experience as if death just passed me by. The momentary lost of sense in front of my eyes which I've never experienced prompted me to think whether I was making a right decision to continue the race. I was thinking if I would have dropped out at that moment when I felt ill, I might have felt more responsive as a husband and father
