Medical Risks:
The Thailand Ultramarathon is a physically challenging event and participation in it presents medical risks, many of which can be extremely serious or fatal.
Participation in this event is at the runner’s own risk. In case of medical emergency, runners will be transported to Pang Ma Pha hospital, however, due to the difficult terrain and inaccessibility of much of the course, this may take several hours.
Participants are encouraged to see their own medical doctor prior to the Run. Runners should be knowledgeable about the stress effects attendant to participation in ultra events.
It is important for each entrant to recognize the potential physical and mental stresses, which may arise from participation in this Run. Runners may be subject to extremes of heat and cold, hypothermia, hyperthermia, dehydration, hypoglycemia, hyponatremia, disorientation and mental and physical exhaustion. Run Management will do all they reasonably can to ensure a safe event, but ultimately runners must understand their own limitations. This is an event where it is better to follow the dictates of your body – not your ambitions! Adequate physical and mental conditioning prior to the Run is mandatory. If you have not been able to prepare properly, do not attempt to run!
Runners should appreciate the risks associated with participation in this event. Actions may have to be taken on your behalf under extreme time constraints and adverse circumstances. We will make reasonable efforts to give assistance whenever possible. Ultimately and primarily you are in charge, and you are likely to be solely responsible for creating your own crisis that we must then respond to. Be careful, be responsible, and do not exceed your own abilities and limitations. IN THE EVENT THAT A RUNNER REQUIRES EMERGENCY EVACUATION THE RUNNER ASSUMES ALL FINANCIAL OBLIGATIONS CONNECTED WITH THIS SERVICE. RUN MANAGEMENT IS NOT RESPONSIBLE FOR ANY DEBTS INCURRED.
Some of the main risks of the Run, but certainly not all of them, are listed. These should be understood and remembered by all runners, before and during the event. Please note that death can result from several of the risk conditions discussed below or from other aspects of participation in the Thailand Ultramarathon.
Renal Shutdown: Cases of renal shutdown (acute renal failure) have been reported in other ultramarathons. Renal shutdown occurs from muscle tissue injury which causes the release of myoglobin, a protein material, into the blood plasma. Myoglobin is cleared from the blood stream by the kidneys and will look brownish-colored in the urine. Adequate hydration will help flush myoglobin through the kidneys. Overwhelming amounts of myoglobin may clog the filtering system of the kidneys either partially or totally. If not treated, renal shutdown can cause permanent impairment of kidney function. IT IS CRUCIAL TO CONTINUE HYDRATING USING ELECTROLYTE FLUIDS DURING THE FINAL HOURS OF THE RUN AND FOR SEVERAL DAYS FOLLOWING THE RUN OR UNTIL THE URINE IS LIGHT YELLOW AND OF NORMAL FREQUENCY.
Heat Stroke/Hyperthermia: Heat exhaustion and heat stroke are serious risks. These conditions can cause death, kidney failure and brain damage. It is important that runners be aware of the symptoms of impending heat injury. These include but are not limited to: nausea, vomiting, headache, dizziness, faintness, irritability, lassitude, confusion, weakness, and rapid heart rate. Impending heat stroke may be preceded by a decrease in sweating and the appearance of goose bumps on the skin, especially over the chest. Heat stroke may progress from minimal symptoms to complete collapse in a very short period of time. Remember that your muscles produce tremendous amounts of heat when running up and down hill. The faster the pace, the more heat is produced. A light-colored shirt and cap, particularly if kept wet during the Race, can help. Acclimatization to heat requires approximately two weeks. It is recommend to train for 90 minutes in 25 degree C. heat or greater for at least two weeks prior to the Run if at all possible. If signs of heat exhaustion occur, we recommend rapid cooling by applying ice to the groin, neck and armpits.
Runners may drink approximately one-quarter or more of their body weight in fluids during this event. This means that an average 68kg runner could possibly drink 17 litres or more of fluid, depending on the heat factor and individual differences. In addition to drinking at checkpoints, runners must carry fluids between checkpoints. To accurately measure fluid intake and output balance, weigh yourself before and after your training runs. This will help you establish your personal fluid requirements (especially during the heat of the day). Remember to replace lost electrolytes lost from sweat along with lost fluids. Every runner has different needs that should be determined during training.
Risks Associated With Low Sodium and Chloride Counts:

Low sodium levels (hyponatremia) in ultramarathon runners have been associated with severe illness requiring hospitalization. It is important for long-distance athletes to use fluids containing electrolytes to replace the water and salts lost during exercise. WATER INTAKE ALONE IS NOT SUFFICIENT, as water intoxication and possibly death may result. This problem may in fact worsen after the Race, as the non-electrolyte-containing fluid which has been accumulating in the stomach is absorbed. Potassium and calcium replacement may also be important, although these levels change less with fluid loss and replenishment.

Signs and symptoms of hyponatremia include; weight gain, bloating, nausea, vomiting, headache, confusion, incoordination, dizziness, muscle twitching/cramping and fatigue. If left untreated, it may progress to seizures, pulmonary and cerebral edema, coma and death.
There are two ways to put oneself at risk of hyponatremia:

  1. over-hydration (with water or even electrolyte-containing sports drinks), and
  2. replacing sweat with hypotonic fluids.

Weight gain of greater than 3% should alert a runner to stop drinking, slow down and allow the body to readjust its fluid status through urination of excess fluids, after which electrolyte fluids or high sodium containing foods such as bouillon cubes can be consumed.

Signs of hyponatremia include weight gain (though this is not necessary for the condition to develop). Higher risk categories are female runners, smaller body size and slower runners.
Risks of hyponatremia can be minimized by acclimatizing to the heat, training the endocrine system, salting foods a few days prior to the Run, matching fluid and electrolyte intake to sweat losses and monitoring weight.
The best way to achieve proper electrolyte and fluid balance is to hydrate with fluids containing proper amounts of electrolytes and to replace with sodium-containing foods or supplements, if required, and as determined during your training. Potassium, while present in many electrolyte-replacement solutions, may also be replaced with fruit, such as bananas or oranges. Beer or other alcoholic beverages should not be taken at any time during the Race.
Electrolyte-containing fluids should be continued after the Race until the gastrointestinal tract is fully functional, which may take several hours. Once the gut is working and adequate hydration has occurred, the normal balance of thirst, hunger, digestion and kidney filtration will maintain the proper balance of fluids and electrolytes.
Effects of Cold/Hypothermia: Temperatures will likely be warm during the run, but be prepared for changeable cold and very wet weather, even during the middle of the race. Hypothermia is a potentially serious risk, especially running late in the evening through to nightfall since one’s energy reserves will have been depleted from 14-16 or more hours of running. Hypothermia can strike very quickly, particularly when pace slows or stops from exhaustion or injury. The initial warning signs of hypothermia often include lethargy, disorientation and confusion. The runner will feel very cold with uncontrolled shivering and may become confused, unaware of their surroundings, and may possibly be an immediate danger to himself. Staying well-nourished, adequately hydrated and appropriately clothed will help avoid hypothermia. It is important that runners have access to warm clothing. You must carry a light jacket and thermals with you at all times.
Wildlife Hazards:
Snakes: There are several extremely venomous and potentially life threatening snakes in this area.
Cases have been reported of death within ten minutes of a bite by these snakes. Parts of this run are in very remote and inaccessible areas. Should you be bitten by a snake, there is absolutely no assurance that aid or help will arrive in time to give you effective assistance. Under no circumstances should any snake be approached.
Spiders, Centipedes and Scorpions: All are present in this area and can inflict very painful bites which can lead to complications if you are allergic to the venom.

Wild Elephants: Occasionally visit parts of the race route.  They are very dangerous animals, and should not be approached under any circumstances.

Village dogs: There are dogs in the villages – be careful – they can bite and may have infectious diseases.

Mosquitoes: Cover up – there have been cases of Malaria and Dengue Fever in this area.

Use of Drugs:

No drugs of any kind should be taken before, during or immediately after the Run. Many drugs can increase the risk of heat stroke. A partial list of problem drugs include amphetamines, tranquilizers, and diuretics.

Injuries From Falling:

Falling is an ever-present danger on the Thailand Ultramarathon, with potentially serious consequences. Parts of the trail are narrow, uneven and rutted with large drops. There are several deep canyons on or very near the trail. Extreme care must be taken.

Muscle Necrosis:

It has been found that some degree of muscle cell death in the legs occurs from participation in the Run. The recovery can take several months. This seems to be a bigger problem in runners who become dehydrated or have overexerted themselves. Medical analysis of blood samples taken from ultrarunners shows that this occurs to some degree in all runners.

Overuse Injuries:

Obviously, innumerable overuse injuries can occur, especially in the knee and the ankle and leg muscles and tendons. Sprains and fractures can easily occur on these rough trails. Blisters may cause you to have a sore day, or in severe circumstances may prevent you from finishing. Competitors must have a working knowledge of how to treat themselves for all of these problems on the trail.

Common Fatigue:

One of the dangers you will encounter is fatigue. Fatigue, combined with the effects of dehydration, hypothermia, hyperthermia, hyponatremia, hypoglycemia and other debilitating conditions can produce disorientation and irrationality.

Getting Lost:

Although Run Management marks the Thailand Ultramarathon course, it is definitely possible to lose the trail. If you believe at any time that you may not be on the correct trail, do not attempt to find your way cross country. If you are 100% sure of your route, backtrack to where you last saw a trail marker and try to find other markers showing the direction of the trail. If you are unable to find your way, stay where you are! Blow your whistle loudly and repeatedly until you are heard. Wandering randomly will take you farther from the trail and reduce your chances of being found.

If you do become injured, exhausted or ill:

STAY ON THE TRAIL. Blow your whistle loudly and repeatedly. You will be found there either by another runner, or the sweeper that monitors the progress of runners during the event. If you feel dizzy, disoriented or confused, do not risk falling. Sit down ON THE TRAIL until you recover or are found. An unconscious runner even a few feet off the trail could be impossible to find until it is too late. If you are assisted by individuals who are not associated with Run Management and you elect to leave the trail, you MUST notify the official at the nearest checkpoint of your decision to withdraw.

Difficulty in Gaining Access to or Locating Injured Participants:

Much of the Thailand Ultramarathon trail is remote and inaccessible by motor vehicle. Accordingly, in spite of the safety precautions instituted by Run Management there is absolutely no assurance that aid or rescue assistance will arrive in time to give you effective assistance should you be bitten by a venomous snake or other wildlife, become sick, incapacitated or injured.

Although medical and other personnel will assist you when possible, remember that you are ultimately responsible for your own well-being on the trail. Only you will know how your body and mind feel at any given time. Monitor yourself during the entire Run, and prepare yourself to drop out at the nearest check-point if you find it just isn’t your day. As you continue past each checkpoint, be aware of the number of kilometers to the next one, realizing that getting rescue vehicles into these areas can be difficult, if not impossible.
There, that doesn’t sound too bad does it?
