Botswana National Stadium opens its first World Athletics Relays on Saturday evening with the 4x100m heats and the 4x400m heats running back-to-back across a tightly packed three-hour session. Forty nations and 723 athletes have travelled to Gaborone for the eighth edition of the championships, and 14 of the 16 World Championships qualifying spots in each relay will be settled across this weekend — with the top two teams in each Saturday heat advancing directly to Sunday's final and an explicit Beijing 2027 entry. It is the first time the Relays have been held in Africa, and the first time the qualification gradient has been this steep.
The men's 4x100m heats are the obvious centrepiece. Botswana, anchored by world 200m champion Letsile Tebogo, will run with home-track lane support that has not been replicated since the 2008 Beijing build-up. Tebogo's split is expected to come from a flying start; the more interesting Botswanan question is whether their second-leg passing remains clean enough to get him the stick at speed. Canada will lean on Andre De Grasse, returning to the senior team for the first time since the Tokyo World Championships, with the third leg likely to belong to Aaron Brown. South Africa, in heat two, are running their strongest combination since 2017 with Akani Simbine on the third leg.
The women's 4x100m heats arrive immediately afterwards, and Jamaica's lineup is the section to watch. Elaine Thompson-Herah, returning to the relay programme after a quiet 2025, is expected to anchor a Jamaican unit that will also include Shashalee Forbes and Briana Williams. The United States will use the heat round to give Sha'Carri Richardson a controlled outing rather than her championship version — a sensible move on a weekend when the priority is moving the stick cleanly through three changeovers, not running 41-low. Britain, in the same heat as the United States, are expected to roll with their indoor 4x60m unit plus Daryll Neita on the anchor.
The 4x400m heats close out Saturday's session and have arguably the deepest spread of medal threats. Belgium are running a full-strength Borlée-era unit including Kevin and Jonathan, while Botswana have entered Bayapo Ndori on the anchor leg in a deliberate echo of the 2024 Olympic relay. Trinidad & Tobago and Jamaica round out the highest-seeded heat. The session-closing women's 4x400m heat features the United States in the same row as Jamaica and Great Britain, with Britain giving Amber Anning the second leg in what looks like an early dress rehearsal of their Beijing baton order.
The wrinkle for everyone is that the heats are not a casual outing. Only the top two from each two-heat run are pre-qualified for Beijing; teams that fall to third or worse have to come back for a Sunday repechage that adds wear to bodies that, in many cases, have an entire summer programme starting in Shanghai-Keqiao two weeks later. Tebogo's coaching team have already confirmed that his Saturday run is his only scheduled outing of the weekend regardless of placing, and several federations have indicated they will rotate athletes between Saturday's heats and Sunday's medal round. The qualification stakes are clear; the management of those qualifications is going to define how the weekend's headlines actually break.
