I don't have any disagreements with the complaints listed below. It was very poorly organized, and I feel like I was completely ripped off.
The one thing I will add is that I inquired with one of the Team Challenge leaders about why their participants (mostly leisurely walkers) were in corrals paced for a 2 hour finish time. He told me that Competitor Group wanted all charity participants in corrals 17 - 19.
Why in the world a professional race organization would cram 8,000 people moving at a pace to complete in 4 hours in front of 20,000 people moving at at pace to compete in about 2 - 3 hours is completely beyond me. It's completely disrespectful to those of us trying to move at our normal pace. Weaving between orange shirted Team Challenge members walking 3 and 4 people across at a pace that would be too slow for my 80 year old Grandmother for the first 12 miles was completely frustrating. I was never able to relax and enjoy the race, because I was constantly looking for ways around people. Competitor Group is 100% responsible for this.
I won't do another Competitor event. This is basic race logic. Horrible, horrible race management.
