The question then is whether you make the rule for the exception or for the vast majority. The related issue is that if you ignore what is happening to the majority, what does that put at risk? Kenyans and Ethiopians did not gain their abilities overnight but over generations. Alaskan Huskies love going for hours, not so greyhounds. African Americans are terrible at swimming but brilliant on the track (and on the NFL field). Europeans dominate skiing, although different geographical groups tend to succeed in short versus long races. In such cases, we have a fair idea of the reasons for success, largely involving genetics, environments or heritage. Can you say the same for greyhounds? |
I have no idea where you dreamt this "rule" up .....perhaps you would like to quote the source?.... I have an article written by Chis Boemo BvSc(Hons) MRCVS titled "Enhancing Performance in Greyhounds" where he states that a greyhound requires 4 DAYS to restore energy/enzyme systems from one race to another.

Wal, I would be interested to know/read what your source did to come up with the 4 day guide. Never heard that before. Bear in mind I can go only on what a range of qualified people say plus what I see in practice on the track. One item of interest was Dr John Kohnke pointing out that dogs which pulled out all the stops in an LAW win probably needed a longer spell to replenish the juices. In any event, race analysis suggests that dogs which took it easier in the first half of the race (Sweet It Is etc) were more able to back up in 7 days. Those two points are consistent with one another. On staying races, the hard facts are that (a) most - say two thirds - run slower times after only a 7 day break and (b) the records are littered with cases of top dogs which fail the second time around - check out Space Star, Xlyia Allen, etc. At the high end of the scale, Marathons have been discontinued now, which is a good thing because analysis showed that the vast majority never, ever, regained their previous form after competing over 900m or whatever. Only a few freaks could do it - see Dancers Reward, for example, but it did nothing for the first 500m. Coming back, it is a fact that the majority of dogs are fading at the end of 500s - this is not a surprise as the greyhound reaches its maximum average speed at around 435m and progressively declines past that. If you were to stick that all on a graph it would confirm the general picture of a breed which is optimised below 500m but where there are obviously some which like something longer - just as humans are split up into sprinters and stayers. The missing element - datawise - is the relative metabolisms of the various sectors, and their breeding, and how that matches the performance records. EG fast twitch and slow twitch muscles and all the rest of it. Meantime, I can go only on what is presented on the track. I can't readily pull up hard evidence of claims by vets, mainly because there is not a lot, and in many cases it is no more than an opinion by a vet rather than a carefully organised study involving large sample numbers. However, if I remember correctly Dr Des Fegan (ex National Tabform) did write something about it. But I will look harder. Irrespective of all that, the greyhound evidence on the track is huge (but not absolute) while the human evidence on quick back ups (footballers etc) is also significantly in favour of the longer break. Thoroughbreds need (or get) even longer breaks. Even the AFL is still arguing about the value of a gap week prior to the finals. It is not precision science but the end result is that you cannot be too sure what any dog will do if it has to back up quickly. Consequently, there is a risk imposed on the health of the animal and on the pocket of the punter. The longer the trip the bigger the impact. It's not a dream, mate, it's the best I can do after sifting the available evidence.
