I'm trying to compile a list of US marathons, from hardest/slowest to easiest/fastest course. I looked on google for such a list but couldn't find anything other than 3 slowest and 3 fastests lists, so now it's up to the Let's Run community! Post all of the marathons you've run, from hardest course to fastest course. Post your times as well if you want to. I've only run 3 marathons, so I'll start the list with that. I'll attempt to combine everyone's list into one big list.
1. Boston Marathon 2:54:21
2. Baltimore Marathon 2:54:29
3. Freedom's Run Marathon (Harpers Ferry) 2:51:58
These 3 courses are all pretty similar, so it's hard to rank them...now add your marathons!
