We were back at Waikoloa for our annual vacation, so I was running at the same place as before. One thing I tried to change this time was to see how far I can get running on the beach south, towards Kona. Turns out, not very far… I run out of sand and came to the very rocky part in about a minute or two. From there, I up the beach, to Marriott and then back to Hilton. At Hilton, I went around the resort once to make this even 4 miles (still very short).
