Your First 70.3
Race Pack Preview
Build three timing scenarios for a 1.9 km swim, 90 km bike and 21.0975 km run. Compare the individual splits, review a practical race-week checklist and print your sample plan. This preview is free; the proposed paid edition is still being developed.
01 / Build your baseline
Mobile shortcut: type 830 for an 08:30 start and 530 for a 05:30 finish target. The conservative and ambitious scenarios adjust swim pace by 5 seconds/100 m, bike speed by 1 km/h, and run pace by 10 seconds/km. These are illustrative variations, not fitness predictions.
02 / Compare three outcomes

Race Stress Test / Wat als het tegenzit?
Pas afzonderlijke tijdverliezen toe op je eigen baseline. De tool rekent opnieuw uit hoeveel marge je hebt en welk looptempo je nodig zou hebben om toch je doel te halen. Dit zijn rekenscenario's, geen voorspellingen of pacingadvies.
03 / Baseline course checkpoints
Estimated elapsed and clock times at major course milestones. These are based on constant pace and the nominal 70.3 distances, not official timing mats or road locations.
| Checkpoint | Distance | Elapsed | Clock time |
|---|
04 / Plan your race morning
Work backwards from your start time. Add your estimated travel, parking, transition setup, warm-up and a contingency buffer. The timeline adjusts when you change the start time. Confirm all official check-in and transition zone deadlines with the organizer.
| Local date & time | Task |
|---|
Enter the actual race-morning closure from the official athlete guide. This is not fetched automatically; leave blank if unknown or if bike check-in is on another day.
The planner uses your device's local timezone. For a race elsewhere, confirm time-zone differences and DST against the event's official local schedule. It does not check real-time traffic or organizer access rules.
Official source record
Record the official athlete-guide link and the date you checked it. TriZentro does not automatically verify or monitor the source.
Not independently verified.
05 / Your race-week checklist
Your checklist is not uploaded. It is saved on this device only if you select Save on this device below; otherwise it is lost when this page closes.
Your race-day decisions
Write down a practical response to three situations before race day. You decide what is appropriate, using the official athlete guide and what you have tested in training. Your choices are included in the downloadable dossier and printout.
Never use this planner to override event safety instructions or medical advice. Do not include sensitive medical information in a shared export.
06 / Your event notes
Make a short personal note about transition access, event cut-offs, nutrition pickup or your contingency plan. This note stays in the browser and is included in your text export.
Check before race day
This is a preparation checklist, not official verification. Unchecked items do not prevent downloading your plan.

Confirm official timings, course rules and deadlines directly with the event organizer.
Race-Day Passport / Wedstrijdpaspoort
Your pocket-size summary of key times, morning departure and your own contingency decisions. The times are estimates based on your inputs, not official course timings.

Print view works without uploading race data. Before relying on it, review all event details against the athlete guide.
07 / Take your sample race pack
Save an editable draft only on this device. Nothing is uploaded and the draft is not saved automatically. On a shared device, someone using the same browser profile could access it.
No draft loaded. You can save your entries when you choose.
This is a prototype, not individualized coaching, nutritional guidance or a guarantee of performance. Course conditions, fatigue and local event rules can change actual results. The future commercial pack would add much more detail, professionally reviewed templates and polished exports. No checkout or payment is active.
