This was my second time running Chicago and it won't be my last! There are crowds cheering you on the whole way and you get the best views of the city. The course is pretty flat with a slight uphill in the last .2 mile. I like to think it really

Great experience!!
the rim 2 rim twin falls race is a great run. Very friendly great crowd and atmosphere. Great food. This is a must for everyone to try.

This race was extremely inspiring to run. I loved every moment of it. Everything was well organized. The packet pickup was a breeze. The race expo was a bit crowded, but the race itself was perfect. The course had great cheering crowds almost the entire route, the marines at every mile
