> The average triathlon finish times calculator shows typical finish times – and approximate swim, bike, run and transition splits – for sprint, Olympic, half Ironman (70.3) and Ironman races by sex, and compares your own time with the average.

## Inputs

- Race type
- Sex
- Your time (optional) – hours
- minutes
- seconds

## Results

- Average finish time
- Swim (approx.)
- Bike (approx.)
- Run (approx.)
- Transitions T1 + T2 (approx.)
- Your time compared with average
- Verdict

## Formula

```
Average time from published race-result analyses · Splits ≈ swim 11%, T1 + T2 4%, bike 50%, run 35% of the total · Difference = your time − average
```

## Explanation

How long does a triathlon take? A typical age-grouper finishes a 70.3 in just under 6 hours and a full Ironman in 12–13 hours. These averages, drawn from large sets of race results, show where you stand.

### How to use the Average Triathlon Finish Times Calculator

- **Race type**
- **Sex**

Averages are approximate and vary with course and conditions; splits are proportional estimates. Everything is calculated in your browser.

### How it works

Choose the race type and sex, and optionally enter your own finish time.

### Tips

- Practise transitions – they count towards your total time.
- Train your race-day nutrition as carefully as your fitness.
- Heart rate zones differ slightly between swimming, cycling and running.
- Everything is calculated in your browser.

### What each result means

- **Swim (approx.)** = [Average finish time]×0.1106
- **Bike (approx.)** = [Average finish time]×0.497
- **Run (approx.)** = [Average finish time]×0.3536
- **Transitions T1 + T2 (approx.)** = [Average finish time]×0.0389

## Worked example

Inputs — Race type: Half Ironman 70.3 (1.9 km / 90 km / 21.1 km); Sex: Men; Your time (optional) – hours: 0; minutes: 0; seconds: 0.

Results — **Average finish time = 5:51:25**; Swim (approx.) = 38:52; Bike (approx.) = 2:54:39; Run (approx.) = 2:04:16; Transitions T1 + T2 (approx.) = 13:40; Your time compared with average = 0 %; Verdict = Enter your time to compare.

## Key terms

- **T1 / T2**: Swim-to-bike and bike-to-run transitions.

## FAQ

**What is a good 70.3 time?**
Under 5:30 is good for age-group men, under 6:00 for women.

**How long does an Ironman take?**
Around 12–13 hours on average; cut-off is 17 hours.

**Why are transitions included?**
T1 and T2 count towards your official time.

**Do courses differ?**
Yes – hilly or hot races are much slower, so compare like with like.
