Every week women up and down the country will stand on the bathroom scales and declare " How could I have gained weight"!
Jockey Ahmed Ajtebi was equally surprised on Saturday evening at Thirsk, but to the envy of women everywhere he stood on the scales to discover that he had lost 1 1/2 pound after passing the post first on Sunbow in the Army Benevolent Fund Maiden Stakes.
Ajtebi said: " I checked in with everything, including my silks, in my hands and when I came back in after the race the scales said 8st 5.5lb and I was told I was a pound and a half underweight.
" This has never happened to me before and I can't understand how it has come about."
Stipendiary steward Adie Smith said: " The rules state that if a rider weighs in more than a pound light, then the horse has to be disqualified, so we had no option."
As well as losing the race Ajtebi was banned for three days for failing to draw the correct weight.
This embarrassing situation occurs very rarely but the most bizarre case happened at Catterick back in 1991.
On the 16th November K Doolan was riding Sexy Mover for trainer Wilf Storey in the Goodwill Handicap Hurdle,and after scooting home by 12 length the jockey weighed in several pound light.
At the subsequent enquiry the rider was asked if anything had happened between weighing out and riding in the race.
The reply was that nothing had happened other than a visit to the toilet due to call of nature.
The mental picture resulting from that statement is not one many people will wish to dwell on!
