A new men's road mile champion will be crowned in Copenhagen on Saturday, and the field World Athletics has assembled suggests the title will be decided by racecraft rather than by raw closing speed. Yared Nuguse is the headline name, but the American arrives at the head of a group deep enough that a mistimed move or a poor position through the first bend could end a medal bid before the closing 400 metres. Vincent Ciattei, Robert Farken, Jake Heyward, Andrew Coscoran and Oliver Hoare are all entered, and each of them has beaten someone in the field this season.

Nuguse's own preparation has been unusually compressed. Saturday's race comes six days after he finished fifth over 1500m at the World Athletics Ultimate Championship in Budapest, a turnaround that several of the championship's road entrants are managing this week. The Olympic 1500m bronze medallist and former world indoor mile record-holder has the strongest road credentials in the field: he won the US road mile title in Des Moines in April in 3:54.06 and has run 3:51.9 on the roads, while on the track this year he was second to Josh Kerr in the world record-breaking London mile in 3:45.69.

Ciattei is the most obvious threat on road-specific form, having finished just over half a second behind Nuguse in Des Moines in 3:54.62 during a breakthrough season that has taken his 1500m best to 3:30.90 and his mile best to 3:48.34. The European contingent is no less credible. Farken, sixth over 1500m at last year's World Championships, ran 3:46.82 for the mile in London and 3:30.09 at the 1500m checkpoint; Heyward finished a place ahead of him in 3:46.73 and has been fourth in the Commonwealth Games mile and fourth in the European 1500m this year; Coscoran took European 1500m bronze in Birmingham and owns a 3:49.26 mile best.

The depth continues well beyond the obvious names. Hoare, the 2022 Commonwealth 1500m champion, was second to Cameron Myers at the Australian Championships in April, while his compatriot Jack Anstey ran 3:55.56 in Dusseldorf on 6 September and contested the road mile at the inaugural championships in Riga three years ago. New Zealand's Samuel Tanner brings a 3:49.51 track mile best and a productive July, and South Africa's Tshepo Tshite, a world 1500m finalist last year, beat Olympic champion Cole Hocker over 3000m in Los Angeles in June. Croatia's Marino Bloudek, a European 800m silver medallist, is stepping up in distance with the sharpest finish in the race.

That spread of profiles is precisely what makes the road mile a different proposition from its track equivalent. There are no lanes, no rails to run off and no rounds to sort the field out in advance, and a single championship race has to settle an event in which 800m specialists and 1500m specialists start on equal terms. The mile and the 5km both run on Saturday, with the half marathon following on Sunday, and the first of those races will tell World Athletics a good deal about whether the road mile works as a championship discipline or simply as a spectacle.
