Heard heavy breathing behind me on the footpath up to the Outwoods. Just what I needed to switch my brain into race mode (it had previously been in mud-wrestling mode ). Managed to hold off my pursuer for the remaining 200 metres or so until the gate into the woods. Took my customary route up the steep climb in the angle between the two main paths from the gate; she didn't follow me.
My dodgy calf still feels OK; let's hope it doesn't stiffen up overnight.
