I hope you figure out good options! We found out that going out all of us together was great fun, but was often a logistics problem and many trips were cut short either in time or distance. Not a problem, unless you're counting on going on the same trips as before, consciously or subconsciously. Training efficiently we did best by ourselves.
I think this is really the thing I learned most about becoming a parent, how to structure my life and prioritize. Before we could just go out and maybe we did this, maybe we did that. Or I could just feel like a long run or ride and just go for it, without any planning. But we developed new habits and routines that worked for us, like most people. It was just a bit frustrating in the beginning until we worked it out.
One of my favourite memories of when my son was tiny is of us XC skiing in the woods where we lived, with baby in a soft baby carrier made for carrying in front, slung on my dh's back and covered with a jacket, as he set off down a hill. I refused to, because my skiing skills are poorer and I was afraid I'd fall, but he was convinced he would stay on his feet (and he did).
I wish you lots of luck. The feeling when they get a little bigger and start really enjoying the world around them is just amazing :-)
ETA: Forgive me if I'm being a bit sentimental here, but I just stumbled over a couple of old photos. For a small child a swing in the park is just as awesome as a climbing trip halfway across the country:
