I heard Kona, Hawaii, is beautiful this time of year. I can attest it is true. I was in Kona for a few days covering a technology story and then the Ironman World Championships, both for Sports Illustrated. The entire day of Ironman craziness is certainly a sight to behold, with over 2,000 athletes grueling out 140 miles swimming, biking and running. The best in the world do this in just over eight hours. It takes others all 17 hours to pull off the feat. I bounced around the transition area most of the day, witnessing the professional start at 6:30 a.m., the super-quick transitions and folks strapping on running shoes for an entire marathon after finishing riding their road bike for 112 miles. More from the Ironman scene is in my Sports Illustrated piece. Check it out here.
