For most runners, there are six core tips that are critical to running an ultramarathon. Each of these tips is (or will be) covered in more detail in other pages.

* '''Hydration'''. ([[Practical Hydration]] and [[Hydration 101]]) Getting hydration right is critical to ultrarunning, and getting it wrong can be very dangerous. In many ways, hydration should be easier in ultras because there is more time to hydrate correctly. Hydration problems in ultras are often due to other underlying issues:

** Bad planning, which results in insufficient fluids being available between aid stations can cause hydration problems.

** Any errors in fueling can cause problems with digestion, which in turn prevents adequate hydration.
