I have seen this talked about in the past, I did a Google search to see what cyclists vs runners think. FYI the Lets Run forum is pretty much the wild west of the Internet and I only skimmed the thread, so you have been warned. I picked two sites, one runner one cycling to be fair. One thing though, I know a lot of ex runners who are cyclists, I don't know anyone who went from the bike to running. I think a lot people get into cycling because they like being fit, being outside and used to run but can't because of the wear and tear of running (and the continuous impact it does).
