Up the hills in the Weir Conservation Land for my noon-time ride today.
From the southeast corner heading northwest up the weir hill trail (singletrack):
Northbound on the Stevens trail (wide, but worn well):
Yes, those are sustained HRs in the low 180's. The complete round trip from my office, through the Osgood Hill conservation land, Half Mile Hill conservation land, and Weir Hill conservation land is just over 9 miles and takes an hour, less when it's dry I'm more fit.
