UK Athletics uses a tool called the Performance Funnel in selection. Its Futures Programme Selection Policy (2024-2025 – the version currently published) lists, under Performance Standard, "Position on the relevant Performance Funnel", alongside a yearly progression profile that "should be rising at least equal to or steeper rate than the event trend". The same policy describes the underlying benchmarks as "derived from the age and stage profiles of Olympic finalists". England Athletics' Junior Talent Programme guide (v5, June 2024) uses the same term, assessing an athlete's "Event Profile" by "position on the relevant performance funnel". The Junior Talent Programme has since been restructured into England Athletics' Talent Development Programme for the 2025-2027 cohort; no more recent public guide using this exact wording has been located.
This page tests that idea against the record, using public World Athletics data, by asking one question: did the medallists themselves stay within that range throughout their development?
We took every Olympic, World and European javelin medallist and finalist, and checked each year of their development against the same funnel. The test is one-sided and deliberately generous: we only count a year as falling short if the athlete's season's best was below the bottom quarter of the medallist range for their age. Throwing further than expected is never counted against anyone.
This page uses javelin data only. Whether the same pattern holds in other events has not been tested here, and should not be assumed.
6 in 10 medallists had at least one season below the line. On the way to their first Olympic or World medal, six in every ten javelin throwers had a season where their best throw fell below the bottom quarter of the medallist range for their age. At European level it was just over half.
One season below the line is normal for a medallist. Because it happened to 6 in 10 of them, a single year below the funnel looks like part of an ordinary path to a medal rather than a sign that an athlete is off track.
Long spells below the line are much less common among medallists. About 1 in 10 medallists spent half or more of their development below the line. Across the wider group of everyone who reached a top 8, it was about 3 in 10. Over several years, the funnel does separate the two groups.
So the question is how the funnel is used. As a description of where medallists have tended to sit across a career, the data supports it. As a pass-or-fail test on a single season, it would have ruled out most of the throwers who went on to win medals in this event.
Position and trajectory together is a different, sharper test, and it does discriminate. The figures above look at position alone, over half or more of a career. This is a stricter combined test, over a shorter window: being below the line and not improving across three consecutive seasons was about twice as common among athletes who reached a top 8 but never medalled as among medallists. The concern behind that judgement is well founded. It also describes the state Vítězslav Veselý was in at 19 to 21, two years before he became World Champion, and Magnus Kirt at the same ages, three years before World silver.
Why javelin in particular: development windows by event and area championships before a first medal.
For each athlete below, this looks at every year from age 18 up to and including the year of their first qualifying result in that group (first medal, or first top-8 appearance), and checks whether their season's best that year fell below the P25 line of the population funnel for their age - the same P25 lines the chart below draws. Olympic/World athletes are compared against the Olympic/World P25 line and European athletes against the European P25 line, never across championship levels. Years with no recorded competition result are excluded rather than counted either way, so the "Athletes" column only includes those with at least one comparable year.
The funnel has two edges, P25 and P75, but only the lower edge (P25) is tested here. Exceeding the P75 line is never counted as a shortfall - a season's best above the population range is not a selection concern, so it is not counted against anyone. This makes the test deliberately generous to the criterion: it looks for reasons to say the funnel failed, not reasons to say it succeeded.
An earlier version of this page compared medallists against finalists who did not medal. Those groups overlapped by athlete, since a thrower can medal at one championship and finish 4th to 8th at another, so that comparison has been removed rather than presented with caveats.

Looking at the two right-hand bands of the table: quite a few medallists had a fair bit of their career below the P25 funnel, sometimes half or more of their comparable seasons, before they won their first international medal. One season below the line says very little on its own.
The top 8 group includes the medallists. These are two overlapping populations, not two independent samples: every medallist is also in the top 8 group. Athletes are counted once per group, on their first qualifying result in that group.
The grey shaded band shows the P25-P75 range of seasonal-best distance by age (dotted black line = median) across all medallists (places 1-3) at the selected Championship Type since 1999. Selecting a specific Championship below overlays that tournament's medallists - shown either as their own P25/Median/P75 by age (solid line = median) or, if "Season's (age) best only" is selected below, as a single line of their best distance at each age. Either way, a large dot always marks the age and distance of their actual medal-winning throw.
Switching "Show medallists/finalists" to "Top 8 Finalists" adds the non-medal finalists (places 4-8) from the selected tournament as thinner, dotted lines in the same place-based colours - season's (age) best only, since a non-medallist has no medal-winning throw to anchor a P25/Median/P75 band around. A largish dot (smaller than the medal dot) still marks the age and distance of their actual performance in that tournament's final, the same way the medal dot does for medallists.
Each athlete's own line or band is built from their entire career at each age, not just performances up to the selected tournament - so a point at, say, age 27 may be drawn from a mark thrown well after the tournament being viewed, if that's when their age-27 season actually fell. The medal dot (or, for a non-medal finalist, the final-performance dot) marks the age they actually competed at that tournament, so you can see which part of the surrounding line or band happened before it and which came after.
Overlaid in purple, using the same P25/Median/P75-or-age-best display mode as the medallists above. A GB thrower who is also a medallist for the selected Championship may appear twice - that's expected.
