Accidental solo half -- Fri. August 17

Wanting to get some mileage in before a rest day I figured I'd try for 10-11 going down the rail trail. But, early evening became later, and so it was too dark to do that safely after the first bit, the ground being dry and hard; left the trail at NWashington and followed that down to the intersection w/ Bardwell. Here, a bit confused re the layout, I went left instead of right, and afetr a while realised there was no connecting N/S road until 181; plodded on anyway, and made it to Michael Sears and then back up (now in real nighttime) to 181, then started the long haul back. Not aiming for speed, but I'd not planned on 12 miles, and this was turning into 13. In the end I stopped to recharge my torch and take a leisurely drink at 11.31, on the uphill just short of town. Then started off again for a very gentle plod of almost two miles to home. Here's how it was:

Time: 1:40:37 (1:25:06 and 15:31)
Distance: 13.25 (11.31 and 1.94)
Speed: 8.0 mph and 7.5 mph

Comment: Happy to have gotten the miles in, but definitely weary. Need to get in some proper weekend long runs again, somehow. A bit worried about feeling v. stiff on Sunday a.m. at Wilbraham, too.
