Diefer, I'm a ride leader with the Princeton FreeWheelers and I have rides out of MC Park 3 days a week. Sunday mornings and Tues and Thurs mornings. Come April 1st, it will be Wed & Fri evenings and Sunday mornings. Also in April they will rotate to 3 different locations. In April the evening rides are different types of training rides, Sunday they are regular rides. The mileage sounds like they are in your ball park. If you want a schedule, shoot me an email.
