And survey says ...

... no running for 4 to 6 weeks.

The ankle is only sprained. I was a bit surprised at getting physical therapy for it, but the doctor talked quite a bit about running injuries and it was clear that she was fairly comfortable in this area (moreso than I, in any event.)

This means the Portland Marathon is out. Maybe I can do the Lost Soles in Talent Oregon in February, but making my first marathon a difficult course in 40 degree weather doesn't sound too fun.
Dude! Sorry to hear of your setback, that sucks. I was enjoying (and being motivated by) your running progress reports.

Have you thought of shifting to another distance sport with less ankle motion? Biking, maybe, or swimming?

Or if you're just after the exercise component, have you tried an elliptical machine? (I believe that's what they're called.)
I was told that stationay biking would be OK, but regular biking is out due to the stresses on the ankle. As for swimming, well, I can't swim very well. I should probably take classes or something. I will be taking some wine classes later this month, but I don't think it's quite the same.

And I don't know what an elliptical machine is, but it sounds scary.
One of these things:

Most gyms have a few. You stand upright with your feet on the pads, which are on guided tracks that describe an ellipse. The motion simulates something between jogging and biking.

I like these because they're no-impact, and they're actually really good for cardio work. It's not scary if you can keep your balance. Most people don't even have to hold on to the handles.
it's true! those are actually pretty fun if you have some music to glide along to. wow...i'm almost inspired to get my butt back to the gym! ;)
Everyone can swim, some just happen to be prettier than others while doing it. Just hop in the pool, pick a stroke and stick with it, you'll get a feel for it after a few laps.

If you really wanna have some fun try to complete the Navy Seal entrance PST:

"500-yard swim using breast and/or sidestroke in under 12 minutes and 30 seconds
10-Minutes rest
Perform a minimum of 42 push=ups in 2 minutes
2-Minute rest
Perform a minimum of 50 sit-ips in 2 minutes
2-Minute rest
Perform a minimum of 6 pull-ups (no time limit)
10-minute rest
Run 1 1/2 miles wearing boots and long pants in under 11 minutes and 30 seconds"

So far I've completed it twice and plan to start training myself by running through it once a week.
That's too bad about the sprain, but good to hear that you have a doctor that is knowledgeable in that area. I'll have to take back all my previous ranting...;)
I do hope you can find some other fitness activity to focus on in the meantime.
Actually a marathon in 40F weather is not bad - you work up a sweat regardless, and you won't notice the cold after the first mile - I promise! I run during the winter myself - and used to run in Colorado in the snow - the only time I stayed in is when ice covers the roads and everything.

Heal up and take care of that ankle - you'll have plenty of time for running when you're better. No need to rush.
ohhhhh....i'm sorry to hear that. but, take care of you first!
you'll be beatin' feet down the street before you know it.
That sucks.
If you do the one in Talent I'll go with you - we can crash at my brother's.
