Cycling’s governing body UCI launched the Champions League to boost the appeal of velodrome racing.
The format features 72 riders, with sprint and keirin disciplines for 18 male and female sprinters and scratch and elimination races for the endurance specialists, all in the space of a TV-friendly three-hour period.
Points are awarded for finishing positions in each race, tallied up over the five rounds of the series to decide the overall sprint and endurance champions.
Race winners earn 1,000 euros (£855) and the overall champions get 25,000 euros, with equal prize money for men and women.
