How long does a triathlon take on average?

It depends on the race distance. The average time to complete a race for different age groups is as follows: Sprint 1:30〜1:45, Olympic 2:45〜3:15, Half 5:15〜6:00 (70.3), and Full Ironman 11:30〜13:30. Beginners are usually in the lower end of these time ranges while elite athletes will be significantly below those times.

How is a triathlon finish time calculated?

The time required for each discipline is calculated based on the distance and pace, with transition times added in. For swimming, divide the distance by 100 meters and multiply that result by the pace per 100m. For the bike leg, divide the distance by the speed, and for running, multiply the distance by the pace per kilometer. The sum of T1 and T2 is the total time.

Are transition times included in triathlon timing?

Yes. As the time is measured from the start of swimming to the finish line, both transition times are part of the official time. T1 is the transition time from swimming to cycling and T2 is the transition time from cycling to running. Beginners can already lose three to five minutes on a single transition, so it's worth working on.

What time should a beginner triathlete aim for?

The real goal in your first race should be to finish. A beginner will usually take two or three hours for a sprint triathlon and about three hours thirty minutes to four hours for an Olympic triathlon. At this stage, consistent pace and smooth transitions are more important than pure speed.

How long does an ironman take on average?

Most participants in the various age groups of an ironman competition finish between 11:30 and 13:30. The bike leg makes up about half of the total race time, making it the biggest segment. Running takes up about a third of the time while swimming is the smallest part. Most ironman races have a maximum time cut-off of 17 hours.

Charts

A triathlon is a race that consists of three disciplines completed one after the other with two quick transitions in between. The overall time depends on the distance chosen and the pace you can maintain while swimming, cycling and running.

This calculator allows you to do two things at the same time. It calculates your estimated finish time based on the swim, bike and run speeds that you enter as well as the distance you select. Then it displays those estimates along with average finish times of participants in similar races with comparable ability so you can gauge where you stand before heading out for a race.

How long is a triathlon?

The four standard distances vary widely. A fit beginner can complete a sprint in under two hours. A full ironman can take more than half a day. Here are the details of each distance and average finish times that participants in those age groups typically achieve.

Distance	Swim	Bike	Run	Average finish
Sprint	750 m	20 km	5 km	1:30 to 1:45
Olympic	1.5 km	40 km	10 km	2:45 to 3:15
Half (70.3)	1.9 km	90 km	21.1 km	5:15 to 6:00
Full (140.6)	3.8 km	180 km	42.2 km	11:30 to 13:30

These averages are based on records from tens of thousands of races. The actual performance on race day depends upon factors such as fitness level, course conditions, weather and smoothness of transitions.

Average finish times by ability level.

The biggest impact on the finish time is skill level. The table below shows typical total times for various distances from beginners to athletes aiming for podiums. The calculator uses average values of each segment as reference points.

Distance	Beginner	Intermediate	Advanced	Elite
Sprint	2:00 to 3:00	1:30 to 2:00	1:15 to 1:30	0:50 to 1:00
Olympic	3:30 to 4:00	2:45 to 3:30	2:15 to 2:45	1:45 to 2:00
Half (70.3)	6:30 to 8:30	5:30 to 6:30	4:30 to 5:30	3:45 to 4:15
Full (140.6)	13:00 to 17:00	11:00 to 13:00	9:30 to 11:00	8:00 to 8:30

Calculation of end time:

The time required for each discipline is calculated by dividing the distance of that discipline by either pace or speed. For swimming, it's pace per 100 meters; cycling, it's speed; and running, it's pace per kilometer. The two transition times are added to get the total time for the entire race.

t_{\text{swim}} = \frac{D_{\text{swim}}}{100} \times p_{\text{swim}}

t_{\text{bike}} = \frac{D_{\text{bike}}}{v_{\text{bike}}} \qquad t_{\text{run}} = D_{\text{run}} \times p_{\text{run}}

T = t_{\text{swim}} + t_{\text{bike}} + t_{\text{run}} + T_1 + T_2

Example: With a swimming pace of 2:20/100 m, a cycling speed of 28 km/h and a running pace of 5:30/km, with the transition time being five minutes, swimming takes about 17.5 minutes, cycling about 43 minutes and running about 27.5 minutes. Adding in the transition times gives an overall time of almost 1 hour and 33 minutes.

Don't forget about transitions.

The two transitions, T1 from swim to bike and T2 from bike to run, are both part of the official time. Although they may seem short, a slow or hectic first transition can cost several minutes. Beginners often need three to five minutes just for the first transition (T1). Practicing your transitions is an easy way to save time without improving physical fitness. If you want to calculate pure training time only, you can disable the calculation of transition times.

Factors that affect race day timing

A flat and windless course can save several minutes over a hilly or windy one, open water swimming is slower than pool swimming, hot weather slows running times, the longer the race distance the more important nutrition becomes, and on bad days an Ironman can take up to an hour longer. Use these estimates as guidelines and adjust them for your particular race.

How to interpret these numbers:

v_bike	Bike speed	28 km/h
p_run	Run pace per km	5:30
