SAFD: Like many others I try to stop for rare characters or the Fab 5 in rare costumes. I don't have anyone I'm particularly hoping to see at this point as I've gotten a lot of pics over the years.
It's officially three weeks since I've done any kind of physical activity. I've got pneumonia again. Last year I got it around Thanksgiving and it wasn't so bad because I was only doing 10K and half. I've been working so hard all year to have consistent training and really set myself up for Dopey success. At this point, I'm feeling very down about my chances of finishing and I have no idea what to do with training. I don't expect to be able to run for another week at least with how I'm currently feeling. Sorry, pity party over now.
Get over the pneumonia first, then back to training. You'll still have appx 2 months to train and that will be enough time to be trained up. You may not be trained back up enough for a Boston qualifying time, but enough to finish. And maybe not as much time as you'd like for character photos, but enough to finish.
Get well, then start a RWR at whatever pace you can manage as you ramp back up. Since basic walking is enough for the 16min/mile pace, I'm sure you'll be able to be more than fast enough for Dopey by race weekend. You've got this.
SAFD: My first couple of rD events (09 and '11) I had very few character stops and the races were over with way too soon. I didn't necessarily go for rare characters, but I did stop for guys like Phineas and Ferb since my sons liked watching them so much.
When I resumed rD again in 2022, it was with an eye toward PR-ing for fun, and that meant running in costume and stopping for good characters. That said, with my kids grown, I haven't watched as much Disney and have run past quite a few characters because I don't even know who the heck they are.
So now it is a case of I'll stop for a character I really like, such as the Mandalorian, or one that is interesting, or maybe if it is a short line. When I did my Dopey, yeah, I'm going to stand in a long line because I want that photo for that race. Another time, as were about to go by the teacups, here comes Alice just walking out. Since the wait was going to be about 1 minute, I jumped in line for that photo op.
So it all depends. YMMV
