I thought this was going to be a complete mess with all the people there. What, 25,000 people? They had several waves and I accidentally put my 5k time down, placing me ahead of the pack. It was a decent race. They shut down several streets, which is always the indicator of a good race for me. Keep in mind, there are a TON of people and you will have some crowded parts. Also, your company will certainly make or break the race for you. Ours had an open bar. No complaints from me :)
