i would agree with this post,, , i would certainly not train them too early in any poss bad weather , these are your future team , sometimes over keenness can force you into hard training , early,, i would suggest this the very wrong thing,to do, yearlings usualy come in to their best form[form that will last longer[ in the month of may,, ] id be far more inclined to wait untill they are on widowhood, ranging well, [being un raced as yb,s will ensure this,,,fresh pigeons] then a few trainers when the weather heats up :-/ ;D] i would be happy just to get a few races under there belt,,,,, then as two year olds ,, the skies the limit,, wish you well
