road race: nothing happened for the first ~25 miles, at which point there was an intermediate sprint. shortly after that, there's a substantial climb that split the field. probably similar to the jericho climb
in your race - somewhere in the 1.5-2 mile range at about 7-8%, IIRC. that was tough. be at the front going into that. then there's a descent that i think has a dirt section. after the descent, nothing else interesting happened until the final climb, at which point everyone just went into survival mode. 2 miles of pain at about 10%, a brief rolling/flat section, and then one last 800m kicker to the finish.
