OMT - so that's over 13kg?
This is from the breeders guide to (I presume) average weights for a conti, and how many points they score in shows for their weight:-
"Table of Points for weight 12lbs 40zs (5.5kg) = 8, 14lbs 4ozs (6.5kg) = 9 points, 15lbs 8ozs (7kg and over) = 10 points."
Both of mine are around 1 year and are around the 6.5 - 7kg mark, but I guess it depends on the individual rabbit.
Was the vet happy with her weight, as it is important that she doesn't get too heavy as it can affect their hearts and joints with the strain of carrying any excess.
