I'm setting the goal of qualifying for the 2020 US Olympic trials marathon. It's honestly a long shot (though not entirely unreasonable), so I need all the help I can get. What are some of the fastest courses out there that qualify?
B standards are 2:19:00 for full and 1:04:00 for half. "The course must be USATF/IAAF/AIMS certified with an active course certification and have an elevation loss no greater than 3.25 meters/km. "
