Ok, so when I had nothing to ride for 3 weeks it was truly no riding at all. Yesterday, I asked at one of the centres I work at, whether they could give me some riding. The result: I rode 4 horses today and I am well and truly happily knackered :)
Another person is going on holiday soon and I can have her youngster and Elementary/Medium dressage horse to ride too.
Cue big smile on my face :)
