sounds like he needs the longer races but also sounds like he was not properly motivated. what nest condition did you send him in, sitting 10 days, small youngster,big youngster, widowhood etc. me i would not give him a year off i would float his first two eggs next year and let him rear a nest of his own, them get him into shape and go to your longest event with him at his best. he sounds like a great pigeon but needs a little extra work. well done for looking after him as many a fancier would have binned him as a young bird.
