No reason not to give it a try. It sounds a lot harder than it really is. Sure the rides are long, but the time limits are generous.
I use randonneuring as motivation to stay in shape like some people use marathons or triathlons or whatever. It's just 5 days a year for a full series so the time commitment is pretty low beyond the 6-10 hours a week of training. I talked a guy at work into riding a 200k with me in April for him to use as motivation to ride his peloton over the winter.
