Full and half blues can be awarded to men and women in both time trialling and mountain biking. See below for the criteria. In other cycling disciplines (e.g., road racing or cyclo-cross), discretionary full blues can be awarded for outstanding performances at national or international standard.

Road criteria

For men, a half blue is awarded to someone in the Varsity Team (top 3 riders in the Varsity Match), who is also within the top 6 riders in the Varsity Match (including Cambridge and Oxford riders). A full blue is awarded to someone who, in addition to the above criteria, achieves within the season two sub-54 minute 25 mile time trials, and a top 50 placing in a national competition (such as the National 25).

For women, a half blue is awarded for someone in the top 3 in the Varsity Match, who also finishes in the top 5 in the BUCS 10 mile TT. A full blue is awarded to someone who meets the half blue criteria and additionally wins one of either BUCS 10 mile time trial or BUCS 25 mile time trial, and come in the top 3 in the other.

Mountain bike criteria

For men, a half blue is awarded to someone in the Varsity Team (top 3 Cambridge riders), who is also within the top 6 riders in the Varsity Match (including Cambridge and Oxford riders), and achieves a top 20 place in the championship category of the BUCS XC championships in the same year. If this second criterion is not achieved, a top 15 placing in the sport catagory in a round of the British Mountain Bike Race Series, or holding a valid Expert or Elite licence will qualify.

For women, a half blue is awarded in mountain biking for coming in the top 3 overall in the Varsity Match, plus either top 5 in BUCS XC or top 3 in a National Series Sport race.

Exceptional performances in other disciplines may be eligible for extraordinary full blues, and may be placed before the men's and women's blues committees, at the Captains' discretion.
