Creatine boosts ATP production by buffering phosphates. When you use your muscles, you have a limited supply of ATP (which is what powers your body). ATP goes to ADP (adenosine TRIphosphate to adenosine DIphosphate). Creatine donates a phosphate to the ADP so it becomes ATP again and can be used immediately for energy.
It will get you a few more reps when lifting, or slightly longer sprints. It's used in high-demand activities. There won't be much benefit, if any, to distance running or high-rep sets (20+).
