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.
- ↑ Once you've become overheated, it can be tricky to cool off enough to recover. Slowing down or stopping is normally required to reduce your heat production. Cold fluids pored over your head, neck and body can help, as can ice. Lying down with your feet elevated can also help.
- ↑ It's unusual for constipation to cause nausea, but it can happen
- ↑ 5.0 5.1 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. I like the lying down option as it helps my legs recover more. It can be helpful to have something to eat and/or drink before you take a nap
- ↑ I've consistently found that if I'm moving at a good pace, I don't suffer from sleepiness. Picking up the pace might help with sleepiness, though this is often impractical
- ↑ There's a difference between having music playing in the background and actively focusing on music. Focusing on the music can be more effective than just having it in the background.
- ↑ I've found that in most ultras there are various low spots. Often it's enough to just keep moving and wait for it to pass.
- ↑ Sometimes crying can be cathartic and release some of the mental pressure.
- ↑ Other runners can provide moral support and a well needed distraction. I've had some wonderful experiences running with others on races. Pacers can also help, especially as they'll focus on your race. Company can be especially beneficial at specific times on a race. The latter part of a race is an obvious time, but also sunset is another critical time.
- ↑ If you have a sleep deprivation headache, I've found that nothing other than a short nap will help.
- ↑ In ultras it's common to get the sense of not making progress, or that the miles have become longer. This is because they have, at least in time terms
- ↑ If you have 20 miles to go, and you're moving at a 15 min/mile pace, think about the 5 hours rather than the distance.
- ↑ If you have 20 miles to go, and you're moving at a 15 min/mile pace rather than your usual 9 min/mile, convert to time (5 hours), then work out how far that would be at your usual pace (about 33 miles). This can be depressing, but it creates a more realistic expectation.
- ↑ 16.0 16.1 16.2 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.
- ↑ The Gastrocolic reflex is the urge to defecate after eating. This is not normally diarrhea, but the strong urge to defecate
- ↑ Drinking more than your intestines can absorb will produce inevitable diarrhea
- ↑ Monkey butt is a euphemism for chafing between buttocks. This condition is more serious than you might expect as it can be surprisingly painful. This is also sometimes called "the ring of fire."
- ↑ 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.
- ↑ When you're exhausted, it is much harder to stay warm.
- ↑ If you wear too many clothes you will sweat and once your sweat has soaked your clothes you will become chilled.
- ↑ Hypothermia is a particular risk at sunset. In most ultras you've been running all days and you're depleted. When the sun goes down you lose the direct warmth of the sun and the air temperature drops. If you also slow up then you have the perfect storm for hypothermia.
- ↑ Sunburn prevents the capillaries in the skin from contracting to conserve body heat, making the cold worse.
