I did CC5K in August. I had just finished my 4th week of C25K. In fact, the morning of the cruise I went for a run in cocoa beach. 8am and the heat and humidity was brutal. I barely made the last 5' running leg. We were on the Dream and it was a double dip. I figured I go for the first day and maybe I would do the second run as well. When we met, I felt like a fish of a different pond. The majority were talking about their half or full marathons, or worse, not talking and just stretching. In the end a family with 2 college kids came in and the parents were joking about being the last ones as they would walk it. In the end, it took me 42' - I did a C25K plan and then walked and run another 5' to the finish line. The humidity was brutal, but all the water stations placed around helped tremendously. So I wasn't the last one, nor the first one. In fact, I noticed a few actually did a 10k run. The CMs were there at the end (one actually ran it) and helped taking a picture of me finishing it. They did wait a bit longer for a few more folks. Oh, and no medals. They discontinued them and they say they will introduce new ones. Finally, have someone else get the CC5K shirt for you, or else, you won't find sizes. Or, wait till later in the day when they will replenish for the next cruise from the back. Regarding 12+, they could not register anyone under, but they said it was up to the parent, but to be conscious about the heat.
