"These horses are running fast."
Translation:Эти лошади бегут быстро.
It worked for me, it may be that this sentence is giving more emphasis on быстро, so it's put at the end instead. With others, the emphasis is placed on the verb, but since running already has a speed implied (as opposed to walking, trotting, etc.), the emphasis is more on the quality of the verb than the verb itself. I could be mistaken, but from reading other comments on other questions, that's what I'm deducing. This is on the mobile app, p.s.
Gallop is one way a horse runs. Horses also "trot" and "canter".
I recall a local horse-training who taught riding and also rented out horse by hour for locals to ride. He was adamant that his horses could not be ridden at more than a canter. If a rider galloped a horse, the riding session was over, and the person was banned from ever renting a horse again.
I'm missing something. If бегать is an abstract verb, intended to indicate a general action, then shouldn't the correct English translation be "These horses run fast"? "These horses are running fast" indicates that they are running right now. Wouldn't this verb aspect require Бежать, then?
