We are currently in the process of having an arena put in *yipee* but for years and years I have only ever had a field to school in/jump in. I try not to when it is very wet as it just ends up as a mud bath.
We only have 3 acres so cant afford to churn up too much. I will ride when wet but am careful as to how the ground goes.
Wouldnt risk riding when really muddy as wouldnt want to risk pulling shoes or injuring horse.
I have 5 acres and have sectioned off a schooling area at the back of the stables (35m2) works well for about 7 months of the year. last year i got a tonne of non toxic sand and added that to the outside track ( clay soil)which has helped alot, it keeps it from getting too solid when the gound gets hard and helps them to grip if its a bit wet.
However i dont ride on it if its muddy as i am the nutter that has to level it with a lawn roller afterwards.
I can also jump if the ground is good, I am building a small x-country course over the full 5 acres cant wait till thats finished.

I don't have anywhere to school as my horses on kept on Paddock Paradise system and I don't have any spare land. I do all my schooling when I am out hacking. Every turn we make is a considered and a controlled turn, all transitions are practised properly, quiet lanes are good for serpentines. Halt/back/ leg yield etc are all done as a matter of course hundreds of times during an average 6 mile hack. If we are lucky enough that it has rained, puddles are brilliant for teaching straightness and using as 'markers' for other movements. Short stretches of wide enough grass verge act as a good discipline for canter transitions up and down. The options are endless and not as boring as being in a school.
