I live one mile from a trail head and work one mile from another. So I can leave work and take the long way home, about 10 miles door to door with 8 of it in the mountains. I like bailing out for this one on Friday afternoons in the summer.
Monday I did a loop - about 5 miles on our paved pathways-8 miles in the mountains and out a canyon for one more paved mile (give or take it was a 14 mile loop)
