RunTri's picks: the best Half Marathons in the US. In Alphabetical order:

Among the most popular marathons, which ones are Hardest/Toughest? Which ones are Fastest/Easiest?

New for the 2011-2012 marathon season: we've analyzed 75 of the top marathons in North America -- with 330,000 finishers and 50,000 Boston Qualifiers --  to determine which ones are the biggest, toughest, fastest, and more.

Beyond the numbers, we've got personal experience, having competed in many of the marathons listed here, a total of 85 marathons overall, to add credibility to the rankings.

ToughestBoston is toughest of our top 25, but with a deceptively fastest overall time, being exclusive to the qualified marathoners. Among marathons open to all runners, Los Angeles, Disney World, Portland (Oregon), RnR San Diego and Marine Corps are most challenging, based on average finish times.

Noteworthy: Chicago's 4:43 in 2010 ranked it 6th toughest overall. For more, see our detailed analysis of Chicago Finish Times by Age Group.  


Easiest: There is no such thing as an easy marathon. 26.2 miles is 26.2 miles, and competing in one is an awesome undertaking and an extraordinary achievement. But when it comes to faster marathon courses, Hamilton, Bay State, Pocono Mountain, Sugarloaf and Hudson River top the list.


And yes, we know very well that there are many, many smaller marathons not on this list that are wicked hard. We limited the analysis to these races, representing hundreds of thousands of finishers. For more see our Complete Marathon Coverage, and more detailed analysis, below.

    Important Notes and Caveats for data that factors into 2013 schedules, slots, etc.

    1. Consider this analysis as best estimates based on current data
    2. Events, Dates and Kona or Vegas Slots -- are based on data published on race web sites as of 12/5/12
    3. Our listed estimate of participants per race is the number we expect may have entered by race day
    4. The listed estimate of participants is NOT necessarily the number currently registered
    5. A unexpected wide variety of things can change between now and race day for certain events; examples:
    -- a race's Kona slots have been known to change with little notice
    -- weather or other conflicts may impact the race distance or race date
    -- sometimes races open additional entry opportunities after being declared Sold Out
    6. Mandatory: for latest and most accurate information, visit the event race sites or ironman.com
