How to Use This Calculator
  1. Enter your Current T1 time (swim-to-bike) and Current T2 time (bike-to-run) in seconds.
  2. Set Practice Sessions per Week and Weeks of Practice before your race.
  3. Review Projected T1 and T2 times, and Total Time Saved across both transitions.
  4. Use the Drill Session Duration and Total Practice Sessions to build your schedule.
  5. Check Season Time Saved over a 5-race season to quantify the cumulative benefit.

What each input means

Current T1 time (seconds)
Your current swim-to-bike transition time in seconds. Typical beginner: 180-300s, intermediate: 90-180s.
Current T2 time (seconds)
Your current bike-to-run transition time in seconds. Typical beginner: 90-180s, intermediate: 45-90s.
Practice sessions/week
Number of dedicated transition practice sessions per week.
Weeks of practice
Number of weeks you plan to practice transitions before your race.

What each result means

Total time saved (sec)
Projected total seconds saved across both transitions after practice.
Projected T1 (sec)
Estimated T1 time after practice period.
Projected T2 (sec)
Estimated T2 time after practice period.
T1 time saved (sec)
Seconds saved in T1 from practice.
T2 time saved (sec)
Seconds saved in T2 from practice.
Wetsuit removal (sec)
Estimated time for wetsuit removal within T1.
Helmet + shoes (sec)
Time for helmet, shoes, and bike grab in T1.
Rack + helmet off (sec)
Time to rack bike and remove helmet in T2.
Shoe change (sec)
Time for shoe change and gear grab in T2.
Drill session (min)
Recommended duration for each practice drill.
Total practice sessions
Total number of practice sessions over your training period.
Season time saved (min)
Minutes saved across a 5-race season.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Current T1 time (seconds) = 180, Current T2 time (seconds) = 90, Practice sessions/week = 2, Weeks of practice = 8 = 4 input(s) provided
  2. Calculate Total time saved
    Total time saved = t1TimeSaved + t2TimeSaved
    53.9 = 53.9
  3. Calculate Projected T1
    Projected T1 = max(t1Floor, currentT1Seconds - t1Gap * t1Improvement)
    142.7 = 142.7
  4. Calculate Projected T2
    Projected T2 = max(t2Floor, currentT2Seconds - t2Gap * t2Improvement)
    73.4 = 73.4
