If we define "Hull" as the midpoint between the MKM Stadium (which is where the rugby league team Hull FC plays) and Craven Park (which is where the rugby league team Hull KR plays), then "Hull" is half way down Brazil Street off Holderness Road - which, incidentally, is where ex-Hull City player Ken Smales lived when he was a lad.
From there, as the crow flies, using Google, the distances to the Gallagher Premiership Rugby sides' stadiums are:
Leicester Tigers 84.82 miles
Saracens 148.37 miles
Northampton Saints 107.34 miles
Harlequins 158.89 miles
Exeter Chiefs**
Gloucester 152.68 miles
London Irish 156.11 miles
Newcastle Falcons 103.24 miles
Wasps***
Worcester Warriors 130.93 miles
Sale Sharks 86.60 miles
Bristol Bears**
Bath**
The bits in brackets are for the people who spend whole days posting about rugby league, as a demonstration of how little they care about rugby league.
** ****ing miles away, forget it.
*** not even the name of a real team, surely. Anyway, it's 102.39 miles.
