Christian, Holden and Kennaugh competing
Three Manx riders are competing in the Tour of California.
Firstly, Anna Christian and Lizzie Holden will ride for the Drops Cycling team in the Women's race which starts later today.
It runs through to Sunday when the Men's edition will get underway.
Peter Kennaugh is in the Team Sky line-up and will be hoping to put behind him last year's event when he suffered a broken collarbone which severely disrupted his season.
