Weltklasse
Zurich

One Evening, the Whole Sport

The first Weltklasse was run on 12 August 1928, and the bill was simple: get Paavo Nurmi. Around 3,000 people came to the Letzigrund — a dirt track that the LC Zürich club had laid four years earlier — and watched the Finn win the 5000 m in 15:18.3. For years the public simply called it the Nurmi meeting: one star, one night, and a habit was born.

The habit grew into the sport's biggest one-night show. By the 1980s the meeting had earned the name it still carries — the Olympic Games in one day — because that is roughly what the start lists were: nearly every reigning champion, in one stadium, settled inside three hours. The Letzigrund was rebuilt in 2007 as a 25,773-seat athletics bowl, and it still fills: the 2026 edition sold out faster than any in the meeting's history.

On the calendar, Weltklasse has sat at the top of whatever circuit existed. It was a pillar of the Golden League from 1998 to 2009, became a founding meeting of the Diamond League in 2010, and shared hosting of the series final with Brussels through that decade. In 2025 the whole final came to Zurich across two days — the opening events staged on the Sechseläutenplatz, the city's opera square, before 26 finals at the Letzigrund. In 2026 it was the last regular stop of the tour, one week before the Brussels final.

The Book of Record Evenings

The meeting's record book opens properly with Sebastian Coe. On 15 August 1979 he took Filbert Bayi's five-year-old 1500 m record by thirteen hundredths with 3:32.03. Two summers later, on 19 August 1981, he ran the mile in 3:48.53 — a race big enough that BBC television broke away from its evening news to show it live. The record lasted seven days before Steve Ovett took it in Koblenz; Coe answered in Brussels nine days after Zurich. That was the sport in 1981, and Zurich was its main stage.

The distance era belonged to Haile Gebrselassie. In 1995 he took roughly eleven seconds off Moses Kiptanui's 5000 m record with 12:44.39, a run voted Performance of the Year by Track & Field News. Two years later came the evening nothing has matched: on 13 August 1997, inside seventy minutes, Gebrselassie lowered his own 5000 m record to 12:41.86, Kenya's Wilson Boit Kipketer broke the steeplechase record with 7:59.08, and Denmark's Wilson Kipketer ran 800 m in 1:41.24 — three world records before the crowd had finished its first drink. Kipketer was not even done: eleven days later in Cologne he lowered his mark again.

Then the book closed for a long time. Yelena Isinbayeva's 5.06 m pole vault of 28 August 2009 — one centimetre over her own record, cleared at the first attempt — turned out to be the last world record the Letzigrund would see for seventeen years. It is also the only mark in this ledger still unbroken: no woman has vaulted higher outdoors since.

The Duel Before Seoul

The meeting's most famous night produced no record at all. On 17 August 1988, Zurich staged the first 100 m between Carl Lewis and Ben Johnson since Johnson had beaten him at the Rome World Championships the year before. The Letzigrund got the rematch the whole sport wanted: Lewis won in 9.93, Calvin Smith split the two at 9.97, and Johnson — the world record holder — finished third in 10.00.

Five weeks later they met again in the Olympic final in Seoul. Johnson crossed the line first in 9.79, tested positive for stanozolol, was disqualified, and the gold went to Lewis at 9.92. The dates are the story: before the most examined race in Olympic history, it was a Wednesday in Zurich that put the two men on the same track — because only an invitational can simply pay to build the race everyone wants to see.

Two Records in Forty Minutes

On 27 August 2026, the drought ended twice in one evening. Alison dos Santos ran the 400 m hurdles in 45.80, taking down the 45.94 Karsten Warholm had run in the Tokyo Olympic final of 2021 — a record that had stood for more than five years and that many considered out of reach. The Brazilian's previous best, 46.29, dated from his world title in Eugene in 2022.

Less than forty minutes later, Masai Russell cleared the last barrier of the 100 m hurdles and stopped the clock at 12.09, with the wind gauge reading exactly zero. Tobi Amusan's 12.12 from Eugene 2022 was gone too. Dos Santos's run was the 26th world record in the meeting's history and the first since Isinbayeva in 2009; Russell's, minutes later, was the 27th. Both marks now go through the routine ratification process.

The rest of the card would have carried the night on its own. Audrey Werro won the 800 m in 1:53.70 — a Swiss record and a Diamond League record, and the third-fastest run in the history of the event, behind only Nadezhda Olizarenko's 1:53.43 from 1980 and Jarmila Kratochvílová's 1:53.28 from 1983 — with Femke Broeders-Bol second in a Dutch record 1:54.71. Julien Alfred beat Melissa Jefferson-Wooden by a photo finish, both at 10.70, a St Lucian record. Armand Duplantis won the vault at 6.25 on his first attempt, with Emmanouil Karalis's 6.20 a Greek record in second. The evening before, the vaulters had opened the meeting inside Zurich's main railway station, competing for the first Zurich Trophy.

Two weeks on, the night read like a dress rehearsal for the season's finale: at the first World Athletics Ultimate Championship in Budapest, dos Santos beat Rai Benjamin and Warholm — the three fastest men the event has known, in one final — for the title in 45.98, and Werro outran Keely Hodgkinson for the 800 m crown.

Meeting Night Is Sponsor-Kit Night

Zurich holds a special card in that universe: it is a brand's hometown. On was founded in this city in January 2010 — the same year the Diamond League began — and still designs everything at its Zurich lab. The rest of the circuit's wardrobe is the familiar one: the Nike Pro Elite line, adidas and the team kits of the professional running groups, all of it sponsor issue rather than national issue.
