Stay Hydrated

The key to a good run is making sure you drink enough water before you start — guzzling water during your run can cause cramps and make you take a lot of bathroom breaks. Drink about 15 to 20 ounces of water an hour before you go for a run; if it's a fast or long run, you should take along a water bottle to sip from as well.
