How it works (according to OP) is you have 
            3 weeks then 3 weeks, then six weeks after the end of you last 3 
            weeks the vaccine kicks in and your horse is at top immunity ie. 12 
            weeks after the first shot. So doing it at end October is still ok, 
            it is more dangerous to do it too early. Ideal time according to OP 
            is 1st september to 1st november.
             
            I agree, my vet has 
            always said as early in Sep as possible, as our rains are coming 
            earlier and our winters are milder each year.
             
             
            Yes, you must remember that a horse of the 
            veld in good condition weight wise and that has previously been 
            conditioned to a fairly good level of fitness, can complete a 30km 
            ride if ridden sensibly. This has been proven, and with no harm to 
            the horse. You will have six weeks, more than enough 
            time.
             
             
            Ah, but remember that my 
            horses aren't "off the veld".  They have spent the 
            winter languishing amidst an overabundance of oat hay, alfalfa and 
            teff, being ridden for an hour a day max, usually in the school or 
            leisurely strolls around the block.  Basically becoming fat and 
            unfit.
             
             
            Also according to OP, you can work your 
            horse the 1st and 3rd week of each shot if they show no sideeffects. 
            The only horses that need complete rest are those reacting to the 
            shot.
             
            I've also asked OP how 
            you can tell if a horse is "reacting to the shot".  
            "Elevated temps" seems to be the answer, but I think 
            that's a crock, because elevated temps are usually a sign that 
            they're getting the virus, not reacting to the shot.  The 
            horses I've seen who have had reactions to the shot have given 
            indications of damage to the heart and liver.  No way of 
            telling that.  I err on the side of caution.
             
             
            Toc should be fine, but 
            PG will be the horse from hell!  For some reason, he stores 
            energy when he's on a lay-off and is downright stupid when brought 
            back into work.  He bolted with me on Saturday, because a 
            plover divebombed us.  I ask you!!!
             
            Don't worry, I've been divebombed by a 
            dungbeetle (I mean really don't tell me it couldn't see our butt the 
            size of a house) and i was nearly dumped, I managed to save myself 
            but then nearly fell off because of the fits of 
            laughter.
             
             
            I could make some crass 
            comment about it knowing shit when it sees it, but I won't.  
            That is seriously funny.
