Doh! That reminds me - I still need to sign up for the Goofy. DW and I are planning a kids-free trip that will basically be "we go down for marathon weekend, we both run a race, and then come home" - I'll see all the parks, but not for long, and not much will be open.
Anyway, just find a good C25k program, go to a running store to get good running shoes, and remember that:
1) walk breaks are fine, especially when you first start out
2) DLF>DNF>DNS (Or, Dead Last Finish beats Did Not Finish beats Did Not Start)
3) cotton is rotten - cotton shirts, shorts & socks are evil, created in the pits of Hell specifically to torture runners.
4) Vaseline and Body Glide are your friends
