Feature Notes And Updates

A public version of the project log: what changed, why it matters, and how the bigger Triathlon Lab features are meant to work.

Race hubs

Race pages combine pro and age-group context, route through unified series hubs, and expose course details when they are available.

Browse races Open IRONMAN Hamburg

Athlete profiles

Unified profiles connect race history, source identities, photos, relay rows, pro context, and age-group results in one place.

Search athletes

Kona planning

The Kona Slot Finder helps age-group athletes compare qualifier fit, and race hubs can show slot projections plus age-graded target times.

Feature briefs

What each feature is for

Each section gives the short version first. Open it for the details, the data it connects, and how it should be used.

Complete athlete profilesAthlete pages are meant to be the single place to understand who someone is, where they have raced, and how their results connect across the site.More details

Unified pro and age-group context where the underlying athlete records can be linked cleanly.
Race-history rows connect back to race hubs, series pages, result tables, and source-backed context.
Profile pages can show relay results without making team finishes look like individual results.
Athlete photos now use top-cropped framing so headshots are less likely to cut off faces.
Search is optimized for direct athlete lookup first, then decorates visible rows with ranking and result context where available.

Race hubsRace hubs bring together the race catalog, results, course data, Kona context, and source history around one stable series page.More details

Series pages are the preferred destination for race browsing instead of one-off source pages.
Headers can show brand, distance, location, course-type chips, water or air temperature context, route links, and course descriptions.
Pro and age-group views can live on the same hub while keeping the visible metrics matched to the selected mode.
Championship merge work keeps older IRONMAN and 70.3 World Championship editions attached to the canonical race hub.
The race catalog uses cached summary fields where possible so browsing is faster and more consistent.

Rankings and scorecardsRankings separate official standings from Triathlon Lab scorecards so users can switch between series position and race-fit analysis.More details

Official rankings answer who is leading a series, such as World Triathlon, IRONMAN, or T100.
Triathlon Lab power indexes summarize recent pro evidence into sortable scorecards for overall strength and race fit.
Long-course profiles emphasize full-distance and long-course durability evidence.
Middle-distance profiles emphasize 70.3 and T100 evidence so specialists are not buried by full-distance bias.
Split scores break the model into swim, bike, and run signals, then the overall score rolls those signals together with result quality and distance relevance.
Evidence drawers let users inspect the result context behind a score instead of treating the number as magic.

Start-list analyzerThe start-list tools turn a race field into a research workspace for podium picks, split strengths, recent form, and course fit.More details

Start lists link athletes to profiles, scorecards, recent results, and race context.
Scoring changes with the race: full-distance starts use long-course profiles first, while 70.3 and T100 starts use middle-distance profiles first.
Fallback score discounts only apply when the selected race type has to borrow the less-specific profile.
Split views help identify likely swim, bike, and run leaders instead of only showing an overall ranking.
The analyzer is designed to support research, comparison, and show prep rather than pretending to be an automatic prediction machine.

ONYERLEFT board and poster exportONYERLEFT turns start-list research into a draggable tier board and clean export workflow for power-ranking graphics.More details

Tier labels are editable, lanes can be hidden or restored, and the board can move into fullscreen mode.
The athlete pool sorts from the relevant score profile for the selected race distance.
Athlete cards use linked photos, start-list photo fallbacks, and curated local images where available.
Poster preview exports only athletes placed in visible tiers and supports PNG or JPEG downloads.
Long athlete names are fitted inside poster cards so exports look cleaner.

Kona and age-group toolsKona tools help age-group athletes understand qualifier fit, slot allocation context, and realistic target windows.More details

The Kona Slot Finder ranks qualifier options using slot volume, age-group profile, heat tolerance, hill preference, swim strength, and speed profile.
Race hubs can show Kona insight directly in age-group mode.
Projected targets assign age-group winner slots first, then use gender-wide performance pools ranked by age-graded time.
Date matching tolerates one-day race-weekend differences when the race and year clearly align.
Non-finish detail views use visual breakdowns so the page reads quickly.

Ranking explainer

How the rankings work

Triathlon Lab separates official ranking tables from power-index scorecards. That way a user can see the official standings, then switch to a model that is tuned for current form, discipline strengths, field quality, and distance fit.

View rankings

Official series rankings

IRONMAN, World Triathlon, and T100 ranking views keep the official series context visible when that is the right lens.

Triathlon Lab power indexes

Scorecard rankings blend recent results, strength by discipline, distance fit, depth of field, and race-type context into sortable pro profiles.

Distance-aware profiles

Full-distance races lean on long-course evidence, while 70.3 and T100 races favor the middle-distance profile so specialists are not flattened into one generic list.

OpenRank credit

PTN's OpenRank work deserves a nod here: it helped make transparent, sport-specific pro ranking ideas feel normal and useful for triathlon fans.

Rankings are evidence tools, not final predictions. They are best used alongside course profile, start-list strength, weather, travel, and athlete-specific context.
Official rankings answer who is leading a series. Triathlon Lab scorecards try to answer who looks strong for a specific race type right now.
The start-list tools reuse the same distance-aware logic so a full-distance favorite and a 70.3/T100 specialist can be evaluated through the right lens.

How a score rolls up

Step 1

Choose the distance lens

Full-distance races prefer the long-course profile. 70.3 and T100 races prefer the middle-distance profile. Short-course views lean on World Triathlon evidence.

Step 2

Score the disciplines

Swim, bike, and run signals are scored separately so a user can see whether an athlete's value comes from front-pack swim security, bike strength, run form, or balanced consistency.

Step 3

Weight the result context

The model values result quality, field depth, recency, race distance, and discipline evidence instead of counting every finish the same way.

Step 4

Roll up the scorecard

The overall score combines the selected distance profile and split signals, then the page exposes the evidence so the user can sanity-check the ranking.
