I do not see Walmsley running under 2:12, however, I do hope I wrong as I like the guy.
My prediction is Mid 2:11-2:12 for the trials. Probably top 10 with a remote shot at qualifying if a few people have bad days. I think he could potentially crack 2:10 on a flat course.
Mid 2:11 at these trials on this course will be 3rd or 4th.
