Also called Standard sprint. Last updated August 14, 2026.

By Ray Shiraishi

A sprint triathlon is a 750 metre swim, a 20 kilometre bike and a 5 kilometre run, about 16 miles in total. It is the most common triathlon format and the usual first open-water race, with most finishers between 1 hour 15 and 2 hours.

Distance breakdown

  • Swim: 750m (0.47 miles)
  • Bike: 20km (12.4 miles)
  • Run: 5km (3.1 miles)
  • Total: 25.75km (16 miles)

Typical finish times

  • Elite: Under 1 hour
  • Advanced: 1:00 to 1:15
  • Intermediate: 1:15 to 1:30
  • First-timer: 1:30 to 2:00

Ranges, not targets. Course profile, heat and water conditions move every one of these on the day.

Training load

  • Weekly hours: 4 to 7 hours
  • Prep time: 8 to 12 weeks
  • Longest sessions
  • Swim: 30 minutes
  • Bike: 60 minutes
  • Run: 30 to 40 minutes

Each leg of a sprint triathlon

The swim (750m)

Usually open water in a lake, river or sheltered sea. Fifteen to 25 minutes for most people. The hardest part is rarely the distance: it is the first two minutes in a crowd, when breathing is difficult and everyone is moving at once. Starting to the side and behind the front group fixes most of it.

The bike (20km)

35 to 55 minutes depending on terrain and fitness. Courses are usually non-technical and suit a road bike. This is where a first-timer most often goes too hard, arriving at the run with nothing left.

The run (5km)

The same distance as a parkrun, run on legs that have already worked for an hour. Expect 25 to 35 minutes as a beginner and 18 to 25 for a strong runner. Practising the bike-to-run change in training, as a brick session, is what makes this leg feel normal.

Who this distance suits

The default first triathlon for most people, and a genuine speed test for experienced athletes. Long enough to demand pacing and preparation, short enough that a mistake does not end your day.

  • The most widely held triathlon distance, so there is almost always a nearby race
  • The usual first open-water event
  • Trainable on 4 to 7 hours a week over 8 to 12 weeks
  • A road bike or hybrid is entirely sufficient
  • Most people are recovered within a couple of days

Common questions

How long is a sprint triathlon?

A sprint triathlon is a 750 metre swim, a 20 kilometre bike and a 5 kilometre run, roughly 16 miles in total. It is half the Olympic distance across all three legs.

How long does a sprint triathlon take?

Most first-timers finish between 1 hour 30 and 2 hours. Competitive age-group athletes finish in 1:00 to 1:15, and elites go under the hour. Transition time counts toward your total, which surprises a lot of first-timers.

What is a good sprint triathlon time?

Finishing under 1 hour 30 is a solid age-group result on a typical course. Under 1 hour 15 is competitive in most local fields. Compare against the course rather than a universal number, since a hilly bike leg or a choppy swim moves every time on the day.

How long should I train for a sprint triathlon?

Eight to twelve weeks is enough for most people with a base level of fitness, on four to seven hours a week. If you cannot yet swim 750 metres continuously, start from the swim and work backwards, because it is the leg that improves slowest.
