The BBC will have full coverage of the international Six Day Series, which starts in London at the Olympic VeloPark on Tuesday, 22 October.
Britain's Mark Cavendish and Laura Kenny are two of the big names taking part, which sees pairs of riders competing together across a wide variety of disciplines.
The men's events, which include the madison, elimination, derny, 200m time trial and keirin, take place over all six days, while the women's races will be held from Friday to Sunday. There will also be an under-21s event - the 1878 Cup.
Cavendish will team up with fellow Briton Owain Doull, with two other British pairings - Andy Tennant/Matt Bostock and Jon Dibben/Chris Latham - included in the 16 teams taking part in the men's event.
Kenny, the most decorated female track cyclist in Olympic history, is competing alongside Elinor Barker, while fellow Brits Kate Archibald and Neah Evans, and Emily Nelson and Manon Lloyd also pair up.
Dutch pair Yoeri Havik and Wim Stroetinga return to defend the men's overall title, which goes to the team with the best points tally across all legs of the series.
For the first time, the BBC will stream live action from four events of the Six Day Series - in Berlin (23-28 January), Manchester (13-15 March) and Brisbane (3-5 April) as well as London.
