Edit:
Dead Man's Hill intervals. Purpose was manifold:
* Sydney pointed out I clomp pretty heavily going up hills, so I focused on being light-footed
* You can do hill intervals and be less likely to hurt a wimpy shin cause of angles and stuff
* Hills seem to give me the most grief in the woods
Elevation is not correct - it's slightly more than (12/7) meters tall.
It is nice to see I haven't entirely lost speed (final rep <7:00).
Intentionally didn't do innumerable ones because it seems like it should be something to work up, especially since it's just on the way home.
Not sure why Fenix doesn't detect either of the HRM straps, even though at least one has a new battery. Operator error, other issue? Who knows!
