Triathlon Distances: How Long is a Triathlon?
One of the benefits of triathlon is that there are many different distance options for athletes to choose from.
There is a running format and distance to fit with almost any personal goal, no matter what your strengths, motivations, or degree of training time available may be.
While there are some common formats and distances within the sport, there are no restrictions in terms of distances or which order the disciplines are held.
Many events have been around for a long time that doesn’t fit into any of these categories. These events use their natural surroundings instead of trying to fit into a predetermined format. Variety truly is the spice of life!
The sport of running adheres to the principle of equality by having men and women compete in the same format and distances. For professional athletes, this also means that they will compete for equal prize money.
How Long is a Triathlon? It Depends on the Distance
The length of a triathlon can vary, so there is not one simple answer to the question. Most beginning triathletes start with a sprint distance race, but those who are really passionate about the sport will often try an Olympic distance or long-course triathlon at some point during their racing careers.
How Long is a Super Sprint Triathlon?
- 400m swim
- 10km bike
- 2.5km run
The super sprint is the shortest triathlon distance and a great entry point to triathlon, giving you the chance to experience the three disciplines together without having to put in hours of training. Finish one and you’ll be a triathlete!
What’s a good time for a super sprint triathlon? Anything under 1hr and you’re flying. Plenty of beginners just aim to have fun at this triathlon distance and aim to complete rather than compete, so enjoy!
How Long is a Sprint Triathlon?
- 750m swim
- 20km bike
- 5km run
Often the shortest triathlon distance option at many events, but still a decent race to get under your belt. This triathlon distance gives you the chance to really experience triathlon, so you’ll need to incorporate tri-specific skills such as brick sessions into your training.
A brick session is a training set that involves more than one discipline/sports back-to-back. The most common example in triathlon is the bike/run brick, where a bike session will be followed by a run.
What is a good time for a sprint triathlon? Come in under 90mins and you should feel chuffed.
Sprint Triathlon Distances
Fishguard Sprint Triathlon
For those who are just starting out in the triathlon world, a sprint distance race is usually the best place to begin. Sprint triathlons include swimming 750 meters (0.5 miles/2,460 feet), cycling 20 kilometres (12.4 miles), and running 5 kilometres (3.1 miles). A sprint triathlon is a perfect distance for both beginners and experienced athletes who want to improve their transitions.
Average Sprint Triathlon Times
When you look at it from the perspective of a professional triathlete, the word “sprint” makes more sense for an event that can take two hours or more to finish. The time it takes to finish a sprint distance triathlon varies depending on the elevation and conditions, but it is typically around 1 hour or less for professional athletes. Ironman distance triathlons usually finish between 8 and 10 hours for elite-calibre triathletes.
When you look at each leg of a sprint triathlon separately, it seems like a much stronger and more concentrated effort than something like an Ironman, which is a lower-effort race that is more about pacing yourself evenly. In other words, athletes can maintain a higher level of energy output for a longer period. Anaerobic training is the kind of training that requires more endurance. That being low-intensity, high-volume training.
Competitive triathletes looking to improve their performance in sprint and Olympic distance triathlons should focus on speedwork, drills, and fast transitions to build endurance. It is important to come out of the water early, so it is important to learn to swim efficiently. Most of the mileage in a sprint or super sprint triathlon is from biking and running. Even if you’re not a strong swimmer or don’t have a wetsuit, you can still make up a lot of ground on the bike and run.
How Long is an Olympic Triathlon?
- 1.5km swim
- 40km bike
- 10km run
Triathlon made its Olympic debut at the Sydney Games in 2000, and this distance is now accepted as the ‘standard’ distance for World Series racing.
Olympic Triathlon Distances
The Olympic triathlon consists of a 0.93-mile swim, a 24.8-mile bike ride, and a 6.2-mile run, which is double the length of a sprint triathlon.
If you’ve ever seen an Olympic or ITU triathlon on TV or online, you know how intense and efficient professional athletes are. The average pace of the race is just above a 5-minute mile pace.
Average Olympic Triathlon Times
High-level professionals usually finish Olympic triathlons in 2 hours or less. The men’s record by Alistair Brownlee is currently 1 hour and 46 minutes. The average Olympic distance triathlon time for the top age groupers is between 2 and 2 1/2 hours. In other words, Olympic triathlons are not easy. Because an Olympic distance triathlon is twice the distance of a sprint triathlon, most athletes spend over an hour on the bike, only to run 10 kilometres (6.2 miles) directly afterwards.
What is a good time for an Olympic triathlon distance? Under 3hrs is a really solid time
How Long is a Half-Ironman Triathlon?
- 1.9km swim
- 90km bike
- 21.1km run
You might also hear the half-Ironman distance referred to as a ‘middle-distance triathlon’ or a ‘70.3’. The half-Ironman distance triathlon is a gruelling step up from the Olympic distance triathlon and a decent challenge that more triathletes are taking on.
Half & Full-Ironman Distances
Long course triathlon, also known as “Iron-distance” triathlon, encompasses both Ironman and half-Ironman distance triathlon. A Half-Ironman race is also called a “70.3” race because it is the combined mileage for all three disciplines. A full-Ironman distance is 140.6 miles.
The Half-Ironman or 70.3 triathlon consists of swimming 1.2 miles (1.9 kilometres), cycling 56 miles (90 kilometres), and running 13.1 miles (21.09 kilometres), or a half marathon.
What is a good half-Ironman time? Race times are very individual and the course can play a big part. But, for the 35-39 group, a good men’s time is approx. 6hrs, 7hrs for women.
How Long is an Ironman Triathlon?
- 3.8km swim
- 180km bike
- 42.2km run
A full-Ironman triathlon is twice the distance of each leg in a 70.3. The Ironman race consists of a 2.4-mile swim, a 112-mile bike ride, and a 26.2-mile run.
Average 70.3 Half-Ironman Times
The average professional time for a 70.3 is 4-5 hours and 8-10 hours for a full Ironman. Age groupers spend significantly more time on the course. For professional and top amateur athletes, good times on moderately difficult courses can range between 5 and 6 hours for a 70.3 and 10 to 12 hours for an Ironman. For busy athletes who have minimal time training, you can expect to spend 6-7+ hours on a half Ironman and 13+ hours on a full Ironman distance event.
What’s a good time for this triathlon distance? Just completing the distance within the 17hr cut-off is a massive accomplishment! But anything around the 13hr mark for men (30-35) is a solid time; 14hrs for women. Getting under the 11hr mark deserves serious respect!
Other Triathlon Formats
Mixed
Relay
- Swim: 300m
- Bike: 7.2km
- Run: 2km
The Mixed Relay format of triathlon, where teams of two women and two men compete, has gained increasing interest in recent years, especially from the casual viewer. The event made its debut at the Tokyo 2020 Olympic Games, where Great Britain earned the gold medal in a thrilling race.
The Mixed Team Relay format consists of a team of four athletes, male and female, completing a short swim-bike-run effort, before tagging their team-mate. The order will change from 2022 to 2024, with the new order being Female-Male-Female-Male. Exact distances may vary slightly between events.
What this means is that there will be more opportunities for athletes of all levels to compete in Mixed Relay-style events in the future. This is exciting news because it will provide more opportunities for people to get involved in this type of racing.
Super League Triathlon
While there are some standard formats and distances in triathlon, there are no real restrictions, as evidenced by the Super League Triathlon series.
Super League Triathlon races are most often held over short distances, such as 300m swim, 4km bike, and 1.6km run. However, they can be held in a variety of formats.
These hikes include the Triple Mix, Eliminator, Enduro, and Equalizer. These hikes differ from the standard “swim-bike-run” format.
In the Triple Mix, athletes will compete in three separate races with limited recovery time in between each race. The order of the disciplines in each race will be changed. In the Enduro event, athletes have to swim, bike, and run three times, with no break.
Ultra Triathlon
There are always longer or more challenging events available if an Ironman is not enough for you.
For a select few athletes, there are opportunities to race for longer than one day.
There could be multiple races of different lengths with a different number of laps, or there could be stage races where participants race for multiple days. One example of this is the Ultraman Triathlon, which has an annual World Championship in Hawaii.
Extreme (or ‘Xtreme’) triathlon racing may be the answer for those looking for a challenge. While these events are often held over the same distance as an iron-distance event, they are characterized by more challenging terrain and/or temperatures. These conditions require a higher degree of self-sufficiency.
The XTRI World Tour is a set of events that are inspired by the Norseman Xtreme Triathlon. These events are more rugged than standard iron-distance events and will challenge athletes in different ways.
FAQs about Triathlon Distances
It’s important to be prepared for a triathlon by knowing what you’re getting yourself into. There is a lot you can do to prepare and plan for a race, but how fit you are will usually have the biggest impact on how successful and enjoyable the experience is. Below we share a few FAQs regarding triathlon distances.
How can I enter my first triathlon?
To find what meets your needs in terms of location, distance, and format, simply choose one and press the enter button! These days, almost all events can be entered online. There are several race listing resources globally.
Experience tells us that making the commitment to do the first triathlon is a significant part of the process. Having a date gives you a goal to work towards and makes the process feel easier.
What distance should my first triathlon be?
Paralympic athletes usually start with shorter distances Most beginner athletes, including Paralympic athletes, start with a Sprint distance race for their first triathlon. The typical distance for a Sprint triathlon is 0.5 miles (750m) for the swim, 12.4 miles (20km) on the bike, and 3.1 miles (5km) for running. There are also triathlons with shorter distances per leg. Instead of a 5km run, it is often a 3km run.
How much does it cost to enter a triathlon?
The honest answer is… ‘It depends! There is a huge range of different types of triathlon events to choose from. There is a big range in prices for different races, from a simple race put on by a local club to a major international race that is very well-organized and expensive.
Shorter-distance races will be cheaper to organize than long-course races, but there will still be variations in price between different types of races within one distance.
An event that is designed to introduce new athletes to the sport of sprinting may cost as little as £10 to enter. This event is organized by a club and is likely to be in a no-frills style.
The cost of entering an IRONMAN event can be more than 500 pounds. This is because there is a lot of investment required for things such as closed roads, goodie bags, a pre-event banquet, an awards ceremony, extended medical coverage and athlete support, live tracker timing, branding, and bespoke finisher medals.
It’s worth considering that, for most people, an event like this will be the highlight of their year. For many, it will be the culmination of months of training and preparation. Confidence that the event will be well organized and provide a great experience is an important consideration. A high ‘cost’ and excellent ‘value’ can exist together!
To a triathlon beginner, the best piece of advice is to start small and gradually work up to more difficult goals.
Should I join a club? This is a good question and many answers could be valuable and worth exploring. Joining a local triathlon club is one of the best things you can do, like-minded people doing like minding things, its a great family to belong to.
Although it may be nerve-wracking to join a club at first, you will probably be surprised at how good it is. People may think they’re not fast or good enough but don’t be put off because in most cases, they’re wrong.
When you are new to triathlon, it is normal to feel overwhelmed by the three different disciplines, the lack of experience you have in them, the different pieces of equipment, and the range of training advice. You may wonder where to begin.
We all have had to learn at some point, especially if we didn’t grow up doing triathlons. The triathlete community is welcoming and willing to share their experiences with new members. The chances are we have been in the same position as you and have asked a “stupid question” before. Don’t worry about it!
The ages and abilities of members in a local club will typically be varied, as will their goals – from completing a Super Sprint to becoming a champion. If you’re around people who have the same interests as you, you’ll be able to learn a lot in a short amount of time.
Additionally, many clubs also offer coached swimming, cycling, and running sessions, as well as important social events! Some clubs will organize and host their own events. Members will know which local events are the best to enter.
