Thanks all for your encouragement, cautions, and advice.
Fitnesswise, right now I’m in “low reasonable” to “reasonable” shape. I’m certainly not overweight or lazy or anything like that. But I work in an office & haven’t been working out regularly. It’ll take a few weeks for me to run 6-8 mi at a stretch; I’m not there yet. But, I don’t think it’ll be very hard for me to hit 90 min up Si or 120 min up Granite, at least w/o a pack; I’ve always been a much stronger hiker than runner. I’ve picked up a book on outdoor conditioning & will put together a training routine from the advice here and in the book (adjusted for the fact that I can’t stand exercising indoors). I’m on the third day of eating foods that are higher in carbs, lower in fats, than my normal foods, and damn, I feel good.
Objectivewise, I’ve no doubt it’d make more sense to try smaller peaks first. In fact I do hope to be able to go on a smaller climb in mid-August. But it’s Rainier that I can see from my apartment whenever the mountain is out, it’s only Rainier that’ll provide the inspiration for me to train hard the next seven weeks. Training for Rainier right now means *not* doing some other things I'd really like to do. So if I don’t target Rainier in September, I won’t begin training until next year.
I think (?) I understand the reaction toward RMI. In a sense, it’s an assist that lowers the bar of the accomplishment, enabling me to attempt something I couldn’t do this year with my own skills. And I imagine it’ll be less fun to do this with a commercial guide & a group of strangers, than doing this with friends or solo; at least, I can analogize to camping, where there are big trade-offs involved in camping with groups of strangers, friends, or solo. I regret but am willing to accept these trade offs, at least on this trip, for the chance to do this sooner rather than later. And yes, it sure is a lot of money.
These things aside (“Other than that Mrs. Lincoln, how did you like the play?” , I’ve heard only good things about RMI; that they’re total pros, provide as good an experience as can be had on a commercially led trip. If there’s some other aspect to this that I’m not aware of, I’d love to hear about it.
It’d also be great to hear about pros/cons of climbing in September versus other times of year (sounds like earlier in the summer is better?), and what is likely to be spooky about climbing Rainier.
Again, thanks.
