You won’t have the convenience of home (adherence to your usual schedule, access to your favorite trail or track), and that’s OK. Decide to run (with schedule modifications if needed), and you will feel much better about your choices. If you have a running coach, inform her of your plans and ask about modified workouts that you can do anywhere.
If you don’t have a coach, take a look at your schedule and your location, and decide on the days that make sense to do a longer run, a speed workout or some other specific training. Fill in the other days as you can, and allow yourself to take some time off, or active recovery as needed.
Perhaps a long walk on the beach or around the city is the perfect way to exercise while giving yourself a breather from your normal training. You won’t lose fitness from a few modifications. When you can get a run in, use it as a pleasant escape and means of seeing a new place on your own two feet. Take the pressure off and you will have more fun.
