Notes
Pretty nice run, although the pleasantness of the Nicky line (green, wooded, nice trail) for a couple of miles is probably not worth the tedium of the narrow pavement alongside the fast road all the way back from Redbourne for 4 miles. Ran that last section the fastest though, felt pretty good rolling along.
Jogged a couple of laps of the park before going home, to make it up to an honest 12 miles.
