Questions before you try TriZentro
Are the Race Pack and Blueprint available to buy?
Not yet. Our prototype and sample chapters are free. The displayed €19.95 prices are product hypotheses, not active offers. There is no checkout or delivery promise.
Why would I pay if the calculator is free?
You should only pay if the completed edition solves an additional problem for you. The proposed Blueprint will add professionally reviewed examples, printable exercises and expanded guidance. A future Race Pack would add a substantially more polished, reusable and detailed race dossier. If those additions are not valuable, keep using the free tools.
Do I need to make an account or share my race details?
No. Our free planning tools run in your browser. Feedback is also voluntary: you can download it or open an email draft to share it yourself. Check our privacy and transparency page for details.
Can I use TriZentro instead of a qualified coach or race briefing?
No. The tools model user-supplied assumptions, not individual physical fitness, medical readiness or actual course conditions. Always follow event officials and seek qualified individual advice when needed.
NEW · EVENT OPERATIONS
Automate volunteer shift assignments, not just paperwork.
Try our Volunteer Roster Planner: enter anonymous volunteer codes with availability and skills, define staffing requirements, and generate a conflict-aware assignment proposal with visible shortages. Download a CSV roster and check which positions still need more people. Free demo, all local in your browser.
Open the Volunteer Roster Planner. This is a planning aid, not an official safety or qualification check. A future paid service could include real volunteer sign-ups, replacements after cancellations and organizer communication — none of these are available yet.
BUSINESS · EVENT OPERATIONS
Organizing a race?
Alongside free athlete tools, we are researching a service for clubs and organizers: participant briefings, version comparisons and volunteer rosters. Explore the proposed pilot and two free demos.

FOR CLUBS & EVENT ORGANIZERS · NEW DEMO
Turn race rules into one clear briefing.
Preparing different wave starts, transition deadlines and participant instructions is time-consuming. Our free Club Race Brief Builder turns official organizer information into a bilingual timeline for up to six start waves, flags schedule conflicts, saves reusable templates, creates NL/EN participant pages and prepares reviewed, printable event updates when details change.
Try it now: build, copy, download or print a draft for one event. No account and no upload. Event rules are never automatically verified.
Potential business product — not for sale yetFor clubs and smaller organizers, we are exploring a tailored event communication service: collecting the organizer's approved source material, preparing branded participant documents, checking version changes and handing back publication-ready files for final approval. A proposed pilot service could be priced per event; no price or delivery promise is active. Organizations remain responsible for official rules and participant communication.
Open the free Club Race Brief Builder Discuss an organizer pilot
What's free today?
Our Race Dashboard, Finish Time Calculator, Race Planner, Fuel Planner and Race Day Timeline remain available at no cost. The proposed paid editions must provide additional depth and polished tools, not simply repackage the free pages.
Help build the next TriZentro productsHave you tried either free preview? We are looking for genuine triathlon users to tell us what worked and what was missing. This is an optional product test, not a purchase or a mailing-list signup.

Transparency: all prices on this page are market-test proposals, not active offers. We do not yet accept payments or promise delivery dates. Health, training and nutrition content is educational; consult the race organizer for event rules and a qualified professional for personal health advice.
