1400 ft+ total elevation gain with max gradient of 13.5%. Then just as much descending to chop up those quads. Seems complete opposite of all those super fast 2:01-2:04 type courses the Africans normally race on.
This smells a lot like Athens 2004 (which had less total elevation gain than this race but was the hottest marathon ever at 86 °F).
All you need now is a heat wave to spice things up and really opens the door for some underdogs to steal the show. I predict this will be the event of the games.
