What are some short term goals you have made for yourself?

Options
I am trying to think of a goal for myself in terms of fitness. I currently go to the gym 5x a week and my workout consists of cardio for 15 minutes (usually run a mile in 10.5 and then do stairs for the rest) then do strength training/weight lifting for 45-50 min. I do a 90 min ashtanga yoga class sundays that whips my butt as well.

I use to run longer distances outdoors- 3-5 miles- but since moving to the city and getting a 9-5 I haven't figured out quite how to do so. I miss that and may just have to figure it out.

Anyway, I want to know what short term (1-3month or so) goals have worked for you all. I was thinking of maybe running 90 miles in October or taking 3 fitness classes a week (they always work me out more than my individual workout) or maybe walking 10 miles a weekend in Oct...

Let me know what's worked for you :)
