Marathoner, ultra marathoner and Detroit native Dave Krupski likes "creating race courses that are my dream races." He's behind the Daytona 100 in Florida and this coming month he'll debut his Michigan ultra marathon courses: the Lighthouse 100-mile and 50-mile ultras on Saturday, June 10. Dave Krupski, along with northern Michigan runner Dan Oberski, are guests on this episode. They talk with Heather about this upcoming 100-miler that starts at the lighthouse in Petoskey and finishes at the lighthouse at the tip of Traverse City's Old Mission Peninsula. (There's also a 50-mile option; this course follows the second half of the 100-mile race course.) Dan Oberski, who was previously a guest on the podcast, talking about running extra long distances, has been training for next month's Lighthouse 100—his first 100-mile race. Dan and Dave talk about how they met earlier this spring (and ran about 30 miles together on the race course), the allure of ultra running, what runners can expect at this new road running event and more. The two race courses are on pavement, not trail where many ultras take place, but runners will be running almost exclusively on bicycle paths along Lake Michigan, on paved trails and little-used country roads, and through some of the most exclusive areas in Michigan. "All along the way you will enjoy countless unobstructed views of the water," Dave says. The terrain ranges from flat (miles 1-30) to rolling hills (miles 30-100). In addition, the race is near the summer equinox, ensuring runners will enjoy about 16 hours of daylight. "When the sun sets, a full moon will illuminate you throughout the night."
