Chris Dyrek discussed the toughest day in sports, the Ironman Triathlon. This is an event that he has participated in many times. It consists of a 2.4-mile swim, a 112-mile bicycle ride and a marathon 26.22 mile run, raced in that order and without a break. It is widely considered one of the most difficult one-day sporting events in the world. Ironman participants have a limited time of 17 hours to complete the race. They start early in the morning. The swim must be completed in 2 hours 20 minutes, the bike portion in 8 hours 10 minutes and the marathon in 6 hours 30 minutes. Any participant who manages to complete the triathlon in these timings is designated an Ironman. The Ironman World Championship has been held in Kona, Hawaii annually since 1978. Chris has competed in many triathlons including Kona and the Challenge Roth, the world’s largest Ironman competition, held in the Bavarian region of Germany.
