Bare in mind, both he and his wife were totally cycling mad, with the grandfather logging ever mile he cycled throughout his day/week/month/year and life in a series of notebooks still retained by the inlaws. He would cycle at least 60-80 miles each day, weather permitting, and if not, the engineers at the Middlesbrough Bridge Yard, where he worked all his life, made him a stand with tensioners to increase friction for use in the kitchen. He was a committed participant in time trials and appeared to win almost every preWWII medal, trophy, clock etc. on offer, all of which now litter both my, and the inlaws houses. The Bianchi bike he won is still hanging in the rafters of the inlaws barn.
I'm sure it must have taken longer for the total journey, but still a mammoth journey done in very few days.
