Blistering speeds and rainbow jerseys, the Track Cycling World Championships are officially back.
The world's best track cyclists will descend on Santiago from 22-26 October to battle it out for the ultimate prizes in the velodrome.
With a mixture of familiar faces and world debutants, British Cycling will have six defending world champions on the track in Chile, as the event returns to South America for the first time since 2014.
GB matched their best ever medal haul at the last edition, with a mighty 13, and will be back for more silverware this time round.
What events are at the Track Cycling Worlds
Split into the usual sprint and endurance events, there will be 12 Olympic disciplines on show.
The three sprint events consist of the sprint, keirin and team sprint, in which the world’s fastest riders compete, while the endurance events are the team pursuit, madison and omnium.
The omnium is perhaps the most challenging of all, made up of four different races: a scratch race, a tempo race, an elimination race and finally a points race.
There will also be a series of non-Olympic events such as the individual pursuit, 1km time trial as well as individual races for the scratch, elimination and points events, meaning that there will be a total of 22 gold medals up for grabs over five days of racing.
British athletes to watch
Katie Archibald, Meg Barker, Josie Knight, Anna Morris and Jess Roberts have their sights set on a team pursuit three-peat in Chile.
The quartet took the top spot at the 2023 and 2024 event and now have the opportunity for a hat-trick, supported by newcomer Maddie Leech.
Each of the athletes will also compete individually, with Morris looking to replicate her recent individual pursuit success.
Morris has already set two world records in the event this year and will be tipped as favourite to defend her title.
On the other side, Emma Finucane will work alongside a new-look team as the Olympic champion looks to defend her women's team sprint title.
Katy Marchant and Sophie Capewell have not made the trip due to personal reasons but an impressive pool of sprinters are ready to step up to the plate.
Finucane will be joined by two-time world medallist Lauren Bell and three debutants: Rhian Edmunds, Iona Moir and Rhianna Parris-Smith.
Finucane will also be looking to return to the top step of the women's sprint after claiming bronze at Paris 2024.
The men’s endurance squad includes team pursuit Olympic silver medallist Charlie Tanfield, while Josh Charlton, who won silver last year after setting an individual pursuit world record, will be locked on upgrading to gold.
Matthew Richardson will make his highly anticipated return to the World Championship set-up in Chile, and his first in a GB jersey.
The sprinter recently set a new world record of 8.857 seconds in the 200m start flying and has five world and three Olympic medals to his name already.
