The International Cycling Union (UCI) is continuing its analysis of riders' blood values as part of the biological passport programme and has again pinpointed a "small number" of athletes with abnormal readings. Last year, five riders were identified as having manipulated their blood, namely Spain's Igor Astarloa, Ruben Lobato and Ricardo Serrano and Italy's Pietro Caucchioli and Francesco De Bonis.
