I was typically running 4-5 miles/day, 5 days/week at about a 7:30/mile pace. Right now, I can do about 1 mile at an 8:30 pace, and it has taken a couple of months to get to that!
The good news is that riding is like cross-training with jogging. It seems to loosen the parts that tighten from jogging, and vice-versa. If I ever get to where I could combine running & riding, I'll have legs of steel AND a strong heart.
I will also add that my overall balance is much better from riding, and that it uses muscles in my back and stomach that I didn't know existed...
