You know that's not too bad. I propose though, that you make it an objective to ride consistently rather than longer distances. If you can do 30 minute rides at an exercise kind of pace, 6 days a week, you will feel better and gain fitness faster than riding 90 minutes 2 days a week. I'm pretty sure doctors will agree with me on this.

Then, once you're feeling like challenging yourself, you can try longer faster rides.

There's a delightful elderly lady in my neighborhood who just noodles along on her old hybrid bike at probably 6mph but she's out there every day for an hour or so riding residential streets and waving at the dog walkers and enjoying herself and staying in shape.
