^^Amen to the mild winter.
My horse is also in decent shape from enjoying the mild winter and trail rides. I spend most of the winter working on Dressage and basics. Our indoor isn't large enough for my comfort to really work over fences.
My first event is in May, so now starts putting my work together. I suck at remembering dressage tests so I begin riding them now so that it's not so stressful come spring. I spend the first 10 minutes of my flat days (usually 3 rides a week) working at the walk/trot on a long rein to get him stretching and forward. Then I will bring him back on the bit with a ton of transitions and lateral work. As I run through tests, I work on the areas we fumble through. Mid April I have a few schooling Dressage shows to go to. I want to see where we stack up and what could use more work before May. Typically my flat rides last 45 min to 60 min with a light canter out in the field (weather permitting) to allow him to have his fun.
I rotate jumping once a week with hacking out in the field. Since Primo's forte is jumping, I don't feel the need to jump as much. Currently we're working on him choosing a little longer spot (since we both like to climb the fence, bad habit) so we do some grid and set striding work then run through a 3'3" course to end the day. The ride may last 45 min or so and ends with a cooling walk to the back of the property.
Hacking out is not as relaxing and fun for me as it is for him. LOL we'll ride 45-60 at a trot and canter most of the ride. Working up and down hills, doing transitions, extension, collection and a few small log piles. As he becomes more fit I want to start galloping for 10 minutes at a time, but right now, his 5th gear is more like 3 1/2 lol. Luckily we're not timed yet.
Like you, I work full time and also go to school full time. I find early mornings and weekends to be my friend till I can ride late in the evening. Typically, I constructively ride 4 days a week and will try to sneak out for a quick trail ride if I can. Dressage is our nemesis and thus my focus.
If your horse says no, you either asked the wrong question or asked the question wrong
And God took a handful of southerly wind, blew His breath over it and created the horse
