PM- Went to Rocky Bottom after work. Ran up Sassafrass plus down a bit towards Caesar's Head, then back to the car. First 10.6 miles had 3000 ft climbing. Then ran the other way on FHT and back. Got caught in the dark plus a hard rainstorm the last 10 or 15 min. I had my headlamp but batteries were low so I was glad I didn't need it more. Finished with over 18.5 miles and 4600 ft climb in 4:05 or so. Garmin said 5800 ft climb. I didn't see a single person on the trail during my entire run, not one person. Saw a bunch of squirrels, though. Got home after 10:30 pm.
