In our first episode of Kilometre 0 from the 2021 Vuelta a España we meet our audio diarists, James Knox, Pavel Sivakov and Joan Bou. Knox, riding for Deceuninck-Quickstep, is riding for GC in his second grand tour of the year. Sivakov, of Ineos Grenadiers, is in a supporting role in a team that includes Egan Bernal, Richard Carapaz and Adam Yates. And Bou is riding for one of the Spanish wild card teams, Euskaltel-Euskadi, fighting to get in breaks and looking ahead to some of the hilly stages.  Kilometre 0 by The Cycling Podcast is supported by Supersapiens: energy management for committed athletes and coaches.
