Blues Cruise

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

The race offers a 9-hour time limit, making it accessible for newer ultra runners. Aid stations are well-stocked and themed, supported by local ultra runners. A relay option divides the course into four legs for teams of 2-4 runners.

Post-race festivities include a participant buffet and awards. Visit the organization's website for the most recent information.
