Imagine, 800 kayaks lying side by side, end to end in rows on the bank of Little Glen Lake in Glen Arbor. A few yards away, picture 800 bikes hanging in organized racks just off of M-22. Beyond the bikes and across M-22, envision 800 athletes ranging from 14 to 71 years old and hailing from 15 states and countries as far as Switzerland running up the Sleeping Bear Dunes Climb. What you are picturing is the fourth annual M-22 Challenge — which will take place this year on June 9 — and if you’re unfamiliar with where it’s taking place, just know that the athletes will tread on what was named the “Most Beautiful Place in America” by Good Morning America last year.
