They tell me it was 'Weight variation'.
Hard to believe he'd be >1kg heavier unless he was given his kennel-mate's breakfast as well as his own by mistake, so I assume he must be down by >1kg. Fretting ?
Its amazing how much they can lose by fretting. When we went to Romford, the trainer weighed my lad when he left the kennels and then of course he gets weighed in upon arrival at the track. A 45 minute journey and he lost over a kg in bodyweight.
Anyway, I'm sure Mr Sarnies will have all the answers.....
