You may have to carry water to stay hydrated, keep your car or house keys somewhere, bring pepper spray for protection, and retain other important essentials, like identification, but making your partner carry everything around because he or she has a pocket, fanny pack or other handy carryall isn't fair. You should only take along as much stuff as you can carry easily yourself. If you're planning a picnic or other activity to coincide with a run, arrange your schedule so you can head back to home base after exercise and before everything else. You can pack up then and freshen up, too. Your partner will thank you.
