Book Across The Bay - Course Conditions

(updated 2/5/2025)


Experience the Upper Midwest's most unique winter adventure at Book Across the Bay, an event open to skiers and snowshoers of all ages and skill levels!

The 2025 Race course is shaping up to be wonderful!  There is a solid ice base of a minimum of 21” with currently (02/05/25) 3” of snow covering the entire route, and as much as 8 inches forecast in the next 3 weeks leading up to race week.  The course does cross several pressure ridges which have been cut down and inspected regularly for safety, so as always, STAY ON THE TRAIL.

Special Note:  The full course this year is 12 Kilometers long.  This is to achieve the full across the Bay & back goal as well as find the safest ice and pressure ridge crossings.  We also are very fond of Dragon Island and want to make sure folks can loop the island and explore the dragon filled caves at the 5th Rest Station… beware o’ dragons upon the Mainstreet Clinic Station!

What We Do

Book Across the Bay is the upper Midwest's most unique winter event, open to skiers and snowshoers of all ages and ability levels. The 10-kilometer course, which is groomed for both classic-style and skate skiing, follows a route not on land, but over the frozen surface of Lake Superior, the world's largest lake. The event is held at night, and the course is lit by the stars above and up to 1,000 candles in ice luminaries that line the entire route.
