I have been doing the Plaza 10K since 2014 and it's my favorite 10K of the year (I did 13 of them in 2019 so that's saying something). This course usually has great weather since it is in September. The location is easy to get to with lots of parking and lots of port-a-potties! The race management and volunteers are second to none. This was my first 10K and I look forward to it every year. The scenery and the spectators are amazing. If you pick one 10K to do, this is the one to choose.
