The Cost of a triathlon


The cost to take part in a triathlon depends on several factors. Each category has its own price. The prices are higher for charity fundraisers. 


  • Individual: Adult individuals often pay the most to race.
  • Team: When you are part of a team the cost is divided by two or three making it less expensive than if you were racing on your own.
  • Kid/Youth: Many triathlons have races for kids or teens that are at discounted rates.
  • Single or double sport: If you choose to do only one or two of the races, but not the full triathlon, the price is often reduced. 
  • Registration date: There is often discounted rates for early registration

“Share” a triathlon

If you are curious about participating in a race but are nervous about competing in all three sports, you can often choose to be a part of a team. 


Teams of two or three people create relay teams that share the triathlon. Select one or two events and your partner(s) can do the remaining one(s). 


This is a great way to participate in a triathlon for someone new to the sport.


Not all triathlons offer this option. Make sure to review the competition rules to see that relay teams can take part. 


Alternatively, some triathlons offer athletes the opportunity to participate in only one or two components of the race. 


Types of triathlons

There are four different triathlons of varying distances. 

  • Sprint (16 miles): 750-meter swim, 20-kilometer bike, and a 5-kilometer run
  • Olympic (51.5 kilometers): 1500-meter swim, 40-kilometer bike ride, and a 10-kilometer run
  • Half Ironman (70.3 miles): 1.2-mile swim, 56-mile bike ride, and a 13.1-mile run
  • Full Ironman (140.6 miles): 2.4-mile swim, 112-mile bike ride, and a 26.2-mile run


How to train for a triathlon

If you are going to complete in your first triathlon, plan to train for 12 weeks. 


If you are very healthy, fit, and familiar with swimming, biking, and running, an 8-week program could be sufficient. If you are newer to fitness and are learning how to run, bike, and swim distances for the first time, you may want to give yourself up to 16 weeks to train.


Here are some important tips to know to prepare for a triathlon.


  1. Train in all three sports.  
  2. Gradually add distance to your workouts.
  3. Practice transitioning. For instance, one day swim and then get on your bike and ride.  Another day you could bike, and then get off your bike and go for a run.  
  4. Practice changing gear quickly between events.  
  5. Some athletes do a practice run through all three sports.  
  6. Be able to complete the triathlon that you sign up for plus 10% more distance.
  7. Cross-train with resistance-based workouts. 
  8. Rest one to two days per week.


Eating right for a triathlon

Training and competing in endurance sports is very demanding on your body. Eating and hydrating correctly is an important part of being an athlete.


Nutrition during training

Eating when you train is the foundation…


When you train for a triathlon, specialists say that an athlete should eat 1.4-1.6 grams of protein per pound of body weight each day. This means that a 160-pound person needs to eat 100-115 grams of protein per day. 


Source protein from meats, poultry, fish, protein powder/shakes, eggs, beans and rice, and dairy products.


Many triathletes consume 20-30 grams of daily protein post-workout to aid recovery. 



Protein is not the only nutrient necessary for training. Healthy carbohydrates, at 2.5 grams per pound of bodyweight, provide critical energy stores for a person training for long hours each week. 


Nourishing sources of carbs are whole grains, beans, winter squash, potatoes, sweet potatoes, and fruit. 



Many people are cautious about their fat intake. But fat plays a critical role in mitigating inflammation. You can actually eat 20-30% of your total calories in fat.


Look to coconut, dairy products, meats, avocados, olive oil, and nuts for great fat sources.



Training makes you thirsty. Depending on the weather, your gender, size, age, and how hard you train that day, hydration needs vary. Often athletes drink 2-4 liters of water per day. 


Remember to include some electrolyte replacement products in your water to maintain healthy sodium and potassium levels.

Nutrition on pre-race day

It is said that you should do nothing new on the day before and the day of the race. This is not a time to experiment.


Athletes are famous for “carbing up” with mountainous platefuls of pasta the night before the race. But that is not what everyone does. Some people prefer steak, tacos, pizza, or other foods that seem to work well for them.


Most athletes do try to minimize high fat or high fiber foods, so as to not have any digestive interference on the day of the race. This means NO BRAN MUFFINS.


Nutrition on race day

Eat your morning meal about 1 ½ hours prior to the race. Triathletes often eat a little protein and carbs, such as a bowl of oatmeal with fruit and an egg or two. 


You can pack a small bite to eat about 30 minutes before the race starts.


Once the triathlon begins, support your body with regular sips of water and energy replacement products such as bars, gels, chews, or gu.
