Fixing problems in Ultramarathons
From Fellrnr.com, Running tips

The table below lists some of the possible problems you may encounter during an ultramarathon, along with possible causes, treatments and preventions. Continuing a race when you have a problem entails some degree of risk, and these problems can impair your judgment, so use caution. This list is not comprehensive, and is expected to change over time. With all these suggestions, never forget The Golden Rule of Racing, "Never do something in a race you have not practiced in training".
Symptom | Possible Cause | Possible Treatment | Possible Prevention |
---|---|---|---|
Not sure what to do | Unknown | Try the Jimbo Test. Picture three things in your mind; a cold drink, a cheeseburger, and a slice of cake.
You can vary the items to suit your taste. For instance, if a doughnut generally appeals more than cake, then think of a doughnut instead of cake. This test is not foolproof, but it is a good, simple way of evaluating want your body probably wants. |

Notes
- ↑ Even without dehydration, if you're not drinking enough to maintain urine production then you may become nauseated. This is because the hormone that reduces urine output also causes nausea.
- ↑ One of the symptoms of Hyponatremia is nausea.
- ↑ It's unusual for constipation to cause nausea, but it can happen
- ↑ 4.0 4.1 Low fat availability is less well researched than low blood sugar/Glycogen depletion, but there is some anecdotal evidence that ultrarunning can deplete the available fat sources. This is not to say that you run out of body fat, just that you can't mobilize those fat stores quickly enough, combined with depleted intramuscular triglycerides.
- ↑ Some runners recommend napping in a chair, others lying down with your feet elevated.
- ↑ 6.0 6.1 6.2 Imodium (Loperamide) is an anti-diarrhea mediation, but it works by slowing the progress of material through the digestive tract. Some runners find this makes the problem worse, acting like a cork.
- ↑ Not normally diarrhea, but the strong urge to defecate
- ↑ See http://www.aafp.org/afp/1999/1101/p2001.html and http://www.jfponline.com/Pages.asp?AID=5146
- ↑ The calf Muscle helps pump blood, so stopping suddenly can exacerbate low blood pressure.
