Appreciate it's not the direction you're setting off in, but if you find yourself with spare time or want additional miles, the ride between Edinburgh and Peebles (particularly the final 20 miles) is one of the loveliest bits of cycling I've done. The downhill to Innerleithen is spectacular, then 8 miles on a beautiful new bike path alongside the Tweed.
