In simple training mode am i still able to gallop my horses? or would this disable simple training mode?, like to have a big stable so simple training suits me, but not having much luck with 2 year olds and wondered if galloping would help.

go to training menu at top select horses to gallop select lead horse
press on the binoculors and you will see them gallop

Yes you can still gallop them. Are you breeding? My 2yo's were never great untill I started breeding with good horses, even then its hit and miss.

just started breeding, the 2 year olds i buy tended to be rubbish but since using the gallops have improved a bit, even when i buy an expensive winning 2 year old they never seem to run as well for me.
currently having a lot of fun with 5 i bought as 2 year olds, now 4 years old, cost about 400k each and all pref 1m6 +, these are the quickest 5 out of 10, the other 5 have gone hurdling, just landed my 1st major gamble in a 1m6 C3 handicap, Spartacus gained its '30' handicap rating in a 5f maiden and just won by 6l despite being 10lb out of handicap!

I tend to find that if you buy a decent, or semi decent, horse from the auction its form immediately tails off. don't know why, it just seems to happen.

neves_rats. If you buy a horse from auction that has won a claimer etc I always look for ones that win easily at that level. I then run in handicaps till the form sucks so bad that it will be a good price in a claimer. Then lump on and it will win. I also do it with horses that win well at 90 handicaps I run them in Group races til the ratings drop right down then lump on in a 90 Handicap too.

My point was not horses youbuy dead cheap that have won a claimer or seller, I too do as you do, buy one that has won easily and see how many wins you can get out of it. My point is that, you buy a decent horse in the auction, especially NH ones, and, as soon as they hit your stable they go crap, that is seriously annoying, so much so that I have stopped buying any horses in the auction that have decent form.

Unless you just retire them. I do that with group winning sprinters that are sold in the auction. But I totally agree, unless you're lucky enough to come across a world beater in the auctions 9 times out of 10 their form tails off and they are no good for breeding or racing. I often find that buying 2yo's from other trainers during their first season. They win a group race then never some close to winning anything but a seller again!
