There's a lot of excitement today, a kind of nervous energy throughout Kona. Exactly what you'd expect just hours away from the start of the biggest race in triathlon. But the pending mayhem hasn't stopped the masses from enjoying either the serenity of the island, or the large and fantastic expos around town. From prototype bikes to endless pools, we caught it all for our Friday gallery, just one day before the Ironman World Championship race. We also shot some video, which will be uploaded next week. For now, enjoy the pre-race stuff, and come back tomorrow for the race photos.
