If not the month where most marathon take place, April marks the beginning of the spring marathon season (for the northern hemisphere).
At least 60 marathons occur in April.
The most famous is certainly Boston Marathon that will take place on the 16th. This year will be the 111th edition. Boston is the oldest marathon in the world and also maybe the most prestigious. Not everyone can run in Boston. You have to qualify to enter the race. To do so, you need to complete one of the Boston qualifying marathons in less than a certain time, determined by your gender and your age.
This is not a Marathon for an average runner !
You may find a list of the qualifying marathons on Bill’s Boston Marathon Qualifiers Guide.

The world weirdest marathon will be held on the 7th : the North Pole Marathon. It is the only marathon that is run on water (actually on a 6 to 12 feet of ice separating you from the cold Artic Ocean). The registration is now closed for the 2007 edition, but it’s time to register for 2008 daredevils !
