Yesterday afternoon riding up the MUP I looked over at the canyon to my right and saw something moving FAST up the the opposite ridge. Didn't look like a mountain biker (no paved road there, but there are some dirt trails) - then saw it was someone on a horse, going at a fast canter up the ridge. Looked like he was flying!
This morning it was cool and foggy. I've been steadily getting faster over the last week or two - last night I covered my 14 miles home in 1 hour flat. Feeling pretty smug!
