Blues Cruise

The Blues Cruise is a 50K trail ultramarathon held near Reading, Pennsylvania, celebrating its 20th anniversary in 2025. The scenic 31-mile loop circles Blue Marsh Lake, featuring varied terrain including fields, rolling hills, single track, and less than half a mile of public road. The course includes a notable climb called the "Ski Slope" with 240 feet of vertical ascent and an optional water crossing.

The race has a 9-hour time limit, making it accessible for newer ultra runners. A relay option divides the course into four legs for teams of 2-4 runners. Well-stocked aid stations and a post-race buffet enhance the supportive atmosphere. Visit the organization's website for the most recent information.
