The Hammer Series is a series of cycling races organised by Velon in which teams compete against each other to determine the winning formation, instead of individual riders.

[1] The races consist of three days, with each posing a separate challenge, sprint, climb and Team Time Trial chase.

[3] Velon is a cycling media organisation created in 2014 by 11 World Tour teams.
