Is this an ok Schedule for my horse?

Ok so the days I ride my horse varies so i don't have like an exact riding schedule but I usually ride with my friend on a 45min -1 hr trail ride then come back untack and jump or just ride in the arena for about 30 min to almost another hour usually 30 min though. (we sometimes keep the saddle on.) So when ever we do ride that is usually how it goes. I just wnat to know if thats to much work for a horse in one day and I know you shouldn't really ride every day or jump every day so i just want know if i am wokring her to hard. i mean we don't do that much cantering or trotting on the trail. there are a few creek jumps sometrotting up hill or just when we want to and a little cantering. Like I said it varies. Last week we rode about 4 days like that. Thanks for your comments.
