Why are local 2hr+ HM & 5hr+ marathoners allowed to sell out races 6months in advance and keep a sub3 marathoner out?
The issue: For serious runners they don't necessarily know a training cycle during marathon buildup is going to go smoothly and may only want to register as it gets closer to the race (such as 2 months prior) rather than be forced to register 6 month in advance of a half marathon/marathon or, worse, be forced to participate in a lottery registration (e.g. Houston Marathon, RnR New Orleans -> I'm not talking huge ones like NYC/Chicago/Boston here, those are obviously exceptions.)
Bottom Line: Does anyone have a list of the low-key faster marathon courses for the serious but non-elite runner?
