My personal goal is that I get myself back into good shape where I can do a 50 mile bike ride (on my road bike, not mountain bike) by mid October and not feel exhausted by doing it.
Oh, I'm sorry, you didn't mention biking!
Well in that case, another personal goal is to be able to run 2.5 miles, non stop, by sometime in November. Right now I've been so overweight and out of shape that my achilles tendons have been really aching, so I'm sticking to walking/jogging along with bike riding until the weight comes down more.
