I've got 2 horses and work full time my job is also about 45/50 mins commute each way.
As others have said it's double the work and double the money, something to think carefully about. But once you get into the swing of it and if you're organised it's not too bad. I only ride one as the other is basically semi-retired due to age related problems. I definitely wouldn't have time to keep 2 in work. I'm very lucky that my OH helps a lot, we have a really good routine in the morning meaning we can be done in 35minutes. We do all jobs in the morning then all I have to do at night is ride, the yard brings them in in the afternoon. For me it's worth the extra work as I could never get rid of my old boy but did want another horse to ride. But it's hard to fit everything in, once I've got to the yard after work, ridden then have to start grooming the other it's quite late and most nights I'm not back home until after 8pm, I'm really horsey though and literally live, breathe do the office job just to do horsey things so it suits me ok. If you have other hobbies or commitments it may be harder. A good routine is key, we have nets made up for week, turnout rugs stay on overnight so no swapping in the morning. I love it, having 2 has allowed me to keep my darling old boy but still go out and compete on my other. My OH is very supportive though he comes down the yard every morning and often in the week to watch me ride, takes me to shows and clinics every weekend, without his support I'd find it a lot harder. There are quite a few other people who have 2 and work full time so it is doable, being on a yard that offers services helps. When you've done it for so long you get used to it. We haven't got kids or any other family commitments though which plays a big part.
