I did the double stack race this year running the 10K race followed by the 5K race. What a fun race even in the rain!! I loved the challenge of doing both races and that it earned you a special medal. The course was well marked and a fast course.
This year they did attempt a wave start for the 5K - this may need a little more fine tuning in the future but things still went smoothly even with how many people were there.
Overall a great race and I look forward to doing it again

This is a large race and was well organized. The 15K is a unique distance which makes it a lot of fun to run. The atmosphere was fun and the aid stations along the course were great. I was impressed with how smooth everything went that morning.
The course was flat and had the option to be a fast race if you desired.
The expo was very tiny without many vendors. I was expecting to find more vendors to meet and check out products while I was there.
Overall this was a fun race and I will definitely do it again.
