I'm doing the glasgow-edinburgh charity run next month and I've started to do some longer runs. Well long for me my commute to work is two-and-a-half miles. Did a 20 mile loop round edinburgh yesterday, and took the train to Linlithgow this afternoon and cycled home along the Union Canal. I thought I might take the train out to other places like North Berwick and cycle home from there (I live in edinburgh). On the spokes map, though, the roads look like they'll be fairly busy. I'm wondering if there's anyone who can tell me which roads to avoid, nice scenic routes to especially seek out, or if there are any other routes around edinburgh that you'd recommend? Thanks!
