I exercise racehorses. We started with unfit, fat older horses coming off a 3 month break. Horses are ridden 5 days a week, mostly in wide open fields with hills, but they might go to the training track once a week. The barn is about half mile from training fields, we jog out and back.
2 weeks jogging, starting at 1 mile working up to over 2 miles.
1 week jog 1 mile, slow gallop 1 mile.
1 week jog 1 mile, slow gallop 1.5 miles.
3 weeks gallop 2 miles, increasing speed gradually.
3 weeks galloping 2 miles, start slow and sprint at the end. Sprint distance increases from 1 furlong to about 4. Once or twice we will go 3 miles.
This is pretty unusual for race horse training, but that’s just how this trainer does it. The horses are very fit by the end, though some soundness issues may crop up with certain individuals; most of them are bottom level runners with existing problems, and they are managed carefully but it’s tough on them. They race on synthetic so that’s why most of our training is better on turf than the deep dirt training track.
