Voyager 1, one light day away, recognition hike

Voyager 1 is one light day away now. A light-day is about 16.1 billion miles (25.9 billion kilometers). Impressive! To recognize this achievement we'll take a shorter hike or walk of 1.61 miles or 3.22 miles round trip on today's hike. Forgive me, I'm still working on which hike will fulfill this. Suggestions?
