Run one of the World Marathon Majors - these races, pretty much a where's where of the international circuit, are part of a series formed last year with additional prize money for elite runners who do well in all over a two-year cycle, writes Emmet Malone.
London:The lottery for places closes this Friday although you need a British address and a bit of luck to get in that way.
Berlin:There is a lot to be said for running in the German capital but what most visitors come each September for is the speed. Flat and inland (no sea breezes) the course is ideal for doing fast times.
New York:The attraction of this one doesn't need a lot of explaining with two million spectators and the chance to run around Manhattan, across the Brooklyn Bridge and through Central Park.
Chicago:Another great city to run in although few people came away from last week's race with too many good things to say as the heat took a heavy toll on the runners.
Boston:Not the biggest but probably still the most prestigious.
Or one of the countless other options on offer:
Tokyo:Next in line to join the Majors series apparently, Tokyo offers the prospect of running in an amazing city which has become very enthusiastic about its race in recent years.
Connemara:Taking place each April, it's tougher than most urban courses but spoken of very highly among those who have competed.
Havana:Friends mentioned this favourably after competing in the half-marathon last year (there are also five, 10 and 15k events). Takes place in November.
Paris:Perhaps the most picturesque course of all the big city marathons, entries for next spring are open now.
Timbuctoo (Timbuktu):Personally, I've had a hankering to get to Mali since nearly making it there for the African Cup of Nations back in 2002 and this could be the excuse required. See www.fulanitravel.co.ukfor more details.
