Strength goes back down each turn...

[purplehorse]

On one of my horses, I train in Driving, and the strength goes up. I take a turn, and i look at it, and it is back down to where it started the last turn. What's going on?http://www.virtualhorseranch.com/viewhorse.php?horse=1769772 Here is the horse link

Is the diet 100%? Have you tried logging out and in again?

It was the diet, it was still low for endurance. Thanks.
