I have done 10 marathons so far
London Marathon x 3
Edinburgh Marathon
Paris Marathon
Robin Hood Marathon
Barcelona Marathon
Shakespeare Marathon
Liverpool Marathon
Chester Marathon
In order i will put them as
Paris - Loved the city and course, champs elysees, Eiffel Tower etc.
London - Loved the atmosphere, tower bridge and mall. - did set a PB here at one time
Barcelona (Was ill on this marathon so hard to remember the great sites on route)
Chester (PB here) - (Did this sunday, great organisation, course etc)
Liverpool - Good course, loved running through tunnel, Sefton park seemed to go on forever - did set a PB here at one time)
Shakespeare (Shakespeare being two laps puts it at bottom for me but would still recommend - - did set a PB here at one time)
Robin Hood (Great first half through city but didnt like the lake - did set a PB here at one time)
Edinburgh (Had a nightmare on this my fault but went off to fast and didnt like the out and back when i had blown up, seeing for miles ahead and no site of turning round plus not really run in Edinburgh you are straight out of the city)
I'm not too bothered about crowds etc but i love running through citys than country roads but to be honest i like to run any marathon.
