I'm heading to Kona later this week and, in addition to vacationing, will be doing some tri training. I plan to ride on the Queen K highway, but am a little concerned about it being a "highway" and the amount of shoulder space for riding. Is this a dangerous or safe place to train? Are there other places on the Kona side of the Big Island that are good for long hours in the saddle? We're staying in Waikoloa.

As for swimming, are there any safe, sheltered areas for open water swimming in that area? Alternatively, someone told me there's a public outdoor 50 meter pool in Kona, but I couldn't find anything about it on the web.

Thanks in advance.
