Sounds great! I would need a map to remind myself to remember where Kona was.
We stayed on the Big Island for about 10 days. We were based at Hilo and moved around abit. (Farmers' market is simple but interesting stuff that we don't have/it's very expensive for us here in Canada.) We only cycled around the area for 1-2 hrs. each day and did rent a car for about 3 days.
Make sure, if you didn't on other Hawaii trips, buy Kona coffee from there for home. It's hard to get in Canada. Wonderful stuff.
We took a trip up Mauna Kea to view sunset and the stars. There is a world famous research astronomy observatory. I had never seen so many stars at night without the telescope. It was magical.
It drops to below freezing up there from tropical temps. below.
This definitely is not related to jogging or cycling routes.
