Late to the game marathon question:
I am not registered for the full yet (I know it's at 99% & may sell out any minute - I have explored bib options with some TAs in case that happens). I've only been running about 18 months, and I'm still in the process of losing weight but I'm much stronger & more fit than I was 18 months ago. I'm determined that my first full will be at Disney. Although I haven't registered, I've been amping up training as though I am. However, I've yet to get to a 20 mile run-walk training session.
I've done 6 half marathons this year, including the Dumbo Double Dare (and I'll do the Infinity Gauntlet challenge in a couple of weeks). I run-walk, and while I have improved leaps and bounds over my couch potato fitness level 18 mos ago, I'm still a slow run-walker (average now is 13:30-14 min/mile in a half). I have a half next weekend on a fast & flat course, but if I had to register today, my POT would be a 3 hr half (from several months ago), which will put me in one of the last three corrals for this as my first full. (As an aside, I believe Disney will still accept a POT for a late registration at this point - last year I registered for the WDW half around Thanksgiving with a TA & my POT got me to corral I).
Aside from working out my budget, I guess what I'm looking for is whether it's still fun to run-walk the full if you're doing so (a) solo, & (b) at the back of the pack. I'm concerned most of the fun would be killed by worrying about being swept.
I'm sure it'd take me a solid 6 hrs to finish, and while I'm dying to do it, I'm questioning if I should just wait another year until
I'm more fit & can maybe get to longer run intervals to shorten my full marathon time a bit.
