The last thing you want is to get caught in a rainstorm in the middle of your walk. Take a look at the weather report in the morning to see when the best time for your walk would be. If you normally walk at around 5 p.m. but the weather report expects rain, then consider rescheduling your walk for lunchtime. And always carry a charged phone with you in case the weather takes a turn and you need someone to pick you up.
If you're heading out for a long walk, you'll want to make sure that you are hydrated. Try to stay hydrated during the and drink two cups of water at least 30-60 minutes before your walk so it's out of your system (and you won't have to use the bathroom). When you return from your walk, make sure to down a glass of water to rehydrate the body. Avoid any sugary sodas or electrolyte drinks; if you're walking at a moderate intensity, water will do just fine to rehydrate the body.
Toss away the old flip-flops and opt for A good pair of sneakers. This will help with posture during your walk and can also reduce the risk of injury. Plus, if you have the right sneakers on, it can help improve your stride and make walking a longer distance more comfortable.
Dressing in layers can prove especially handy as your body warms up throughout your walk. Try a two or three layer system, with the first layer against your skin being a moisture-wicking material. Depending on the weather, a second and occasionally third layer can provide a barrier from the cold, wind, rain or all of the above. If you heat up, just tie that extra layer around your waist.
