I have ran the Go! Half Marathon 3 years in a row. I absolutely love this race. Yes, many people will complain about the hills. I guess it's a pretty big deal when they have to name a 2 mile section that is almost all uphill (The Holy Hill). However, being from St. Louis and being accustomed to the elevation, I don't mind the hills in this race. I might be kind of weird, but I like long rolling hills. This race is organized by the city of St. Louis and they do a superb job year after year. Everything is so nicely organized, from the Expo to the corrals, to the incredible post race food. Um, yeah, the food...Oh my goodness, I think that is why I PR every year at this race. It is because I am picturing the Ted Drew's ice cream sandwich, the toasted ravioli, the fresh pretzels and those awesome little PB&J graham crackers they hand out after the race! If you are thinking about running this race, don't hesitate. Just do it! The electric atmosphere will spur you on to one of your best races.
