Yeah, just slow down and see how that goes. Don't be afraid to repeat weeks, either -- your legs will probably thank you for it, anyway. Running is so incredibly much more strenuous than walking, it's easy to be shocked by the difference.
If you continue to struggle with adjusting after several more weeks of it, check with a doctor, though, make sure you don't have exercise induced asthma or anything.
