Blues Cruise 50K Trail Ultramarathon

Join us for the 20th anniversary of the Blues Cruise 50K Trail Ultramarathon. The course circles the beautiful Blue Marsh Lake, near Reading PA. The 31-mile loop is very runnable, with a varied terrain that includes fields, plenty of rolling hills, single track and less than .5 miles of public roadway. The “Ski Slope” is the only major climb (240 feet in vertical ascent).

New for 2025: We are moving the race start up 30 minutes to 8:00 AM to allow us to extend our hard cut off from 8.5 hours to 9 hours (finish by 5PM). Aid stations 5 and 7 will have strict cut off times to facilitate this deadline.

The 50K offers a relay option where teams will complete 4 legs of the course. Prizes for the fastest teams, and all registered runners will have access to post-race activities and a buffet.

Race Directors Michael Whalen & Elaine Cook, experienced trail and Ultra runners, along with over 100 support members, ensure an exceptional race experience.

Early registration is $90. Registration closes on September 28, 2025, at midnight.
