Trailer arrived, towbar fitted

Courtesy of an excellent itinerant towbar fitter, I now have the means to pull a trailer and as of this morning, a trailer to pull. All I lack is the body to ride a bike.. The muscles in my chest just scream when I try to do anything involving my upper body with bending, sneezing, coughing or (not much of this) laughing. I made the mistake of trying to sort out my new trailer and I felt something in the region of the pec muscles tear as I did so. I am just praying I shall be OK for my next bike trip to Wales and after that to Slovenia.
