Horses on Lasix get shot up 4 to 4 1/2 hours before race..i.e around 2PM (hotest parts of day) for their 11th race. But Saturday may be a cooler and maybe rainy day. ..horses on lasix get no water, or very limited amounts to wet their dry mouth. Looking at racing form sheets etc will not tell us how young horses do under these conditions. It will be a wait and see down the stretch.
