From the Organizer
From June 1, 2026 through August 31, 2026 run VIRTUALLY from Holland, Michigan, along US-31, to Charlevoix, Michigan!
That's 236 miles! It's essentially the equivalent of going 4 miles on Monday and Thursday and 10 miles on Saturday. We'll "stop" along the way at beautiful lakeside towns as we make our way along the west coast (best coast).
