Triathlon Total Time Calculator
Add swim, T1, bike, T2 and run times for a full triathlon finish time, then get overall pace per kilometre across the total distance.
How it works
Total time = swim + T1 + bike + T2 + run · Overall pace = total time ÷ total distance
A triathlon result is the clock from the swim start to the finish line, which means the two transitions (T1 out of the water onto the bike, T2 off the bike into the run) count against your time just as the three sports do. Athletes often obsess over swim, bike and run splits while leaving minutes on the table in transition. Overall pace across the whole course distance is a rough cross-discipline speed, useful for comparing races of the same format.
Worked example
An Olympic-distance race: 25 min swim, 2 min T1, 70 min bike, 1.5 min T2 and a 45 min run total 143.5 minutes, or 2:23:30. Across 51.5 km that is an overall pace of about 2:47 per km.
Frequently asked questions
Do transitions really count in the total time?
Yes. The race clock runs continuously from the swim start to the finish line, so every second spent racking the bike, pulling on shoes or fastening a helmet in T1 and T2 is part of your official time.
What are the standard triathlon distances?
Sprint is about 750 m swim, 20 km bike, 5 km run (≈25.75 km total); Olympic doubles that to ≈51.5 km; Half (70.3) is ≈113 km; and full Ironman is ≈226 km. Enter the matching total distance to get a meaningful overall pace.
Is overall pace per km a useful number?
It is a rough summary that blends swimming, cycling and running speeds, so it is best used to compare your own races of the same format rather than as a training pace. For training, use each discipline’s own pace instead.
