Hey, for some horses…actually for my horse at the levels he ran at, nearly $95k over five years was pretty good. (He seems, from what I can find, to be far and away the best his dam produced, even if it was for three different owners.) Most of the ones I’ve known who wound up OTTBs have lifetime earnings of mid/low four figures.
And my answer to the original question is “Lots.” Or even OUT of training. The two I have shares in are BOTH on injured reserve and despite one being a G3 winner and the other having two wins they cost more than they earn overall
