Running and biking are quite different in terms of what they work. The only thing they really work the same is your cardiovascular system. I use a bike sometimes when I can't run, and the next day some random muscle or another that I never knew I had is always sore.
Running is much higher impact, but I've known people who have run for 30 years, 40 years, and more. So I wouldn't be too worried.
