One question at a time.

Compare recorded season-best marks or Elo ratings by event, season, country and region. Open an athlete for their results, trends and available top-three/top-five performance averages.

Use marks to compare performance levels; use Elo to explore head-to-head results. Elo is our analytical rating, not the official World Athletics ranking.

Find a competition, open an event and inspect recorded placings, marks and rounds.

Use this to check the underlying competition result behind an athlete’s ranking or analysis.

Compare countries and regions against typical medallist and finalist season bests and world-list depth references. Click a count to see the athletes behind it.

Performance depth measures marks against references. Championship conversion, a separate view on this page, counts entrants, finalists, top-eight finishers and medallists.

Browse meetings by date and location. Open a meeting to inspect its recorded event programme; use Contact details for organiser information.

Programme and contact coverage varies by meeting. Check the organiser’s latest information when planning an entry.

Explore championship marks, ages and season-best histories of medallists and top-eight finishers. See how performance developed across the seasons leading into an outcome.

This describes athletes who achieved those outcomes. Following a similar performance curve does not establish the same chance of success.

Compare placing benchmarks across championships and editions, such as gold, bronze or eighth place.

Useful for comparing historical competition levels. A championship result is different from an athlete’s season best, particularly in tactical races.

Follow recorded performances from early rounds to the final, with summaries and individual athlete journeys.

These are performances by selected finalists, not exact marks required to qualify out of a heat or semifinal.

Choose Middle Distance for 800m and 1500m pacing, positions and finishing patterns. Choose Long Distance for 5,000m and 10,000m championship closing splits.

Coverage varies by race; missing splits are not estimated.

Choose an event to see the 2027 entry standard, historical ranking cutoffs and published upcoming meetings. Expand the calculator when planning a set of performances.

The calculator is a planning estimate. Official eligibility, dates, competition category and federation selection still need checking. Historical cutoffs are not future guarantees.

Explore historical venue/month patterns and meeting categories, then inspect upcoming meetings with a matching programme. Enter an SB to focus on comparable athletes.

Covers outdoor track and field, senior combined events, road running and race walking. Road coverage is limited; unsupported comparisons are left empty. Indoor events and relays are excluded. Historical performance rates do not predict a future field.

Choose Performance journeys, Junior → Senior, or Routes to senior success. The three views look at development from different starting populations.

Use the comparison below to choose the right view. Each has its own coverage; the newer routes view contains additional historical sources.

Compare consecutive recorded seasons using season-best improvement or Elo change. Filter by age, event and geography to build an athlete watchlist.

This is an observed change signal. Check the athlete’s results and sample size, especially when the current season is incomplete.

Combine current SB, best recorded SB and age against a selected championship finalist reference. The chart shows a performance index and projected age at that reference.

The default improvement assumption is 0.5% per year. Age 31 and the two-, four- and six-year lines are planning choices, not biological limits or selection rules.
