My father lives in Waterloo, so I come down and run this race every year. The race starts in George Wyth State Park, which is beautiful. The only downfall to this is that there is one way in, and one way out. So, make sure you get there early as traffic going into the park gets really backed up. I actually jumped out of my dad's car and ran a mile to the starting line as I would have never made it in on time to start the race with the rest of the runners (and I went early!). The course is almost entirely on trails through beautiful parks and I can honestly only think of two hills along the whole course, and they are small. I have my half marathon PR on this course, and expect that many people get their PRs here. The post-race party is also fun and we always stick around for it - delicious pizza, beer, and a fun atmosphere. Great race and I've ALWAYS had perfect weather!
