Think it all depends on what system you race as to wether you train through the week or not,with widowhood most people do not train at all after the first race they just shut them out first thing in a morning for a hour or so amd then same at night,with natural unless you can leave them on a open hole all day I think they need to be trained 3 or 4 times a week depending on the weather.Personally ive never bothered about how far to take widowhood coks or how many times,mine had about 6 tosses before racing started the furthest being about 10 miles.
