Ethiopian athletes have won three of the last four 1500m titles since 2010 - Faith Kipyegon being the interloper in 2012 - and this record is expected to be improved upon in Tampere.
Five Ethiopian U20 athletes have run 13:15 or faster already this season and they will be sending their very best to Tampere in the form of reigning champion Selemon Barega.
Don’t be fooled by the world U20 list. The Ethiopian duo of Girmawit Gebregziabher and Tsige Gebreselama are ranked outside the top 10 on the U20 list at this distance but it would be imprudent to take those times at face value.
Among the biggest favourites on the Tampere Stadium track this week will be rising Ugandan star Jacob Kiplimo, whose career has advanced by the proverbial leaps and bounds since he raced to 10,000m bronze at the last edition of these championships two years ago.
Japan-based Hellen Ekarare Lobun leads the entry lists by a clear margin with 15:12.89 but she was decisively beaten at the Kenyan U20 Championships by Beatrice Chebet, 15:31.66 to 15:46.97.
Staggering. There's no other way to describe Kenyan dominance in this event. In 15 of the championships' 16 editions, the first man across the finish line wore the country’s black, red and green. In 10 of those races, Kenya took home gold and silver. The only certainty at the moment is that there won't be a repeat of the latter - simply because the east African powerhouse has, surprisingly, entered only one athlete in the event.
In an event as unpredictable as the 3000m steeplechase, it may be unwise to assume anything ahead of time, but we can say this ahead of Friday evening’s final: Celliphine Chepteek Chespol looks almost unbeatable.
World U18 champion De'Jour Russell's rise through the ranks is such that he made the Jamaican senior team for the Commonwealth Games in Gold Coast in April, making the final just days after celebrating his 18th birthday.
Chanel Brissett leads the world U20 lists with 12.75 – the second fastest time in history at U20 level – but the 18-year-old still missed out on a place on the US team for Tampere.
Last year, Sokwakhana Zazini left Nairobi as one of the brightest U18 talents on the planet. This year, the 17-year-old South African intermediate hurdler will arrive in Tampere ready to pick up where he left off.
It’s no surprise that success at the IAAF World U18 Championships has a strong correlation with success at the IAAF World U20 Championships, and one athlete who’ll be hoping to continue that trend is South Africa’s Zeney van der Walt, who will be the clear favourite for 400m hurdles gold in Tampere in the absence of world leader Sydney McLaughlin.
Zhang Yao will aim to become the first man in history to complete a full set of global age-group race walking titles.
Mexico’s Alegna Gonzalez and Ecuador’s Glenda Morejon finished first and second over 10km at the IAAF World Race Walking Team Championships in Taicang in May and they will resume their rivalry over the same distance but this time on the track in Tampere.
Spanish heptathlete Maria Vicente added the continental crown to the world U18 title she won last year, scoring a world U18 best of 6221 at the European U18 Championships in Gyor on Friday (6).
Olympic champions Thiago Braz and Dilshod Nazarov top the bill of the 33rd Grande Prêmio Brasil Caixa, the only Latin American stop of the IAAF World Challenge and IAAF Hammer Throw Challenge, on Sunday (8) in Bragança Paulista, in the region of Campinas, Sao Paulo, Brazil.
Organisers of the Meeting International Mohammed VI D'Athletisme de Rabat have assembled some mouth-watering clashes for the men’s 100m and women’s 200m at the IAAF Diamond League meeting in Rabat on 13 July.
Hundreds of promising athletes will be in Finland for the IAAF World U20 Championships Tampere 2018 from 10-15 July. Here are 10 particularly exciting talents to follow next week.
Mexico’s Roberto Vilches finished ninth at the last edition of the World U20 Championships but the 19-year-old leads the world U20 lists with a recent 2.26m clearance and is unbeaten in 2018.
When you break a record that had previously been held by two global champions, it can only be a promising sign.
In the splendid, flourishing career of 18-year-old Armand Duplantis, the world U20 title may eventually be looked back on as no more than a footnote, but for the here and now, this will be all that matters to the Swedish pole vault star.
