Was this past weekend. CtC is a fully unsupported race from Pittsburgh to Philadelphia in odd years, and reverse in even years. It's pretty close to 600km. It's so unsupported that it has been hard to find results. Text the organizer when you finish.
25 riders did it this year, with the first sub-24 hour finish.
I hate bike route S with a passion, so I doubt I will ever ride it.
WHYY had a story.
