Goal Split Planner

Start with the finish time you want, then reverse-calculate the swim, bike, run, transition, checkpoint, and fueling requirements that make the target possible.

Sprint racing may only need water or a small carb top-up, depending on duration and conditions.

Plan Checks

This split shape looks internally consistent. The next check is whether your recent training supports each required pace.

Beginner sprint sanity ranges

Leg	Comfort finish	Solid beginner	Watch-out
Swim	2:30-3:15 / 100 m	2:00-2:30 / 100 m	Pool pace may not survive open water.
Bike	20-24 km/h	24-29 km/h	Overbiking makes the 5K ugly fast.
Run	6:45-8:00 / km	5:45-6:45 / km	Fresh 5K pace is usually too optimistic.

The simple sprint plan

Swim at the pace you can hold while sighting and staying relaxed.
Bike the first half controlled, then decide whether to press.
Start the run slower than fresh 5K pace for the first kilometre.
Practice transition flow once or twice before race week.

Example to compare against

A beginner-friendly sprint plan might be 18:45 swim, 50:00 bike, 33:45 run, and 7:00 total transitions for about 1:49:30. Use it as a realism check, not a required target.

Planning estimate, not a race guarantee

Formula summary

Finish time = swim + T1 + bike + T2 + run, with related tools for risk checks.

Key assumptions

Entered paces, distances, transitions, and condition choices are race-realistic.

Limitations

Weather, course profile, water conditions, equipment, and execution can change results.

Full formulas, source notes, and limitation details are maintained on the methodology page. Use official race guides for event rules, cutoff times, venue policies, and safety instructions.
