The 2026 outdoor track season is upon us, and after a World Indoor Championships that delivered drama, records, and unforgettable performances, the anticipation for what lies ahead could not be higher. With the World Athletics Ultimate Championship in Budapest looming in September as the season's centrepiece, here are the rivalries and storylines that will define the summer.

The men's 1500m rivalry between Josh Kerr and Cole Hocker is the headline act. Their World Indoor 3000m battle in Torun was merely the latest chapter in a rivalry that has captivated track fans since Hocker's shock Olympic gold in Paris. Both men are expected to contest the 1500m outdoors, and the Diamond League circuit will provide multiple opportunities for them to renew hostilities before their likely showdown in Budapest.

Keely Hodgkinson's pursuit of the outdoor 800m world record is the other must-watch storyline. After smashing the championship record indoors with 1:55.30, Hodgkinson looks primed to attack Jarmila Kratochvilova's ancient outdoor mark of 1:53.28 — a record that has stood since 1983 and is widely considered one of the most suspicious marks in the sport's history. If Hodgkinson can replicate her indoor form outdoors, a world record attempt at the London Diamond League meeting could be one of the year's defining moments.

The men's distance events promise extraordinary depth. Jakob Ingebrigtsen will defend his position atop the sport against a resurgent Kerr, the ever-improving Timothy Cheruiyot, and a generation of young athletes emerging from the NCAA system — including Cooper Lutkenhaus, the 17-year-old who stunned the world at the Indoor Championships. Whether Ingebrigtsen targets the 1500m, 5000m, or both in Budapest will shape the season's competitive landscape.

In the sprint events, watch for the continued rise of Julien Alfred in the women's 100m, the emergence of NCAA record-breakers Ja'Kobe Tharp and Garrett Kaalund at the professional level, and the ever-compelling question of whether Noah Lyles can return to his 2023 form after an inconsistent 2025. The 2026 outdoor season promises to be one of the most compelling in recent memory — and it all starts now.
