I live in KC and I will probably watch them climb up the Summit St hill up to 17th from Pennway for about half the race (located at the far western part of the course)
and
Watch them them take that 45 mph left hand turn in front of Union Station at Main and Pershing (very close to the start and finish
and
Maybe the climb up Kessler Rd back into Penn Valley Park up to the WW1 Memorial. (another hilly section)
