Here is my Strava:
Long rides, for me, are a microcosm of all the emotions. In four hours, I ran through feeling proud, smug, bored, elated, resigned, despairing, and back to triumphant. The tl;dr version:
It was so hot. I drank all my water. I didn't electrolyte Dixie enough and she ran out of go-juice at 16 miles, so I got off and walked the last two miles in. I let her graze, and she wasn't in any distress, and when we finally got back to the trailer she dove into her mash and drank a couple gallons of water and pulsed right down. I got blisters on the bottoms of both my heels and a heatstroke-headache.

Before the last two miles, it was quite a bit of fun. Dixie was a perfect angel to meet a random kid in the parking lot. She plugged on up the hills and trotted/gaited the flats and the downhills. Bikes and hikers and dogs didn't phase her, but she had to stop and stare HARD at a kid with a butterfly net. I had him wave it around and she eventually decided it was ok.
I have got to get my shit together and ride with people. I do great on solo 10 mile rides, and I do ok on 15 mile rides, but 20 miles all alone is just so hard mentally. And it's not like I don't have any choice - I have at least four endurance people I could email and meet up with! I just didn't get around to talking to them this week and then last night I was like "must go ride 20 miles tomorrow." Ugh.
I took a bunch of little videos on my phone but splicing them together and uploading them is WAY MORE EFFORT than I can put forth tonight. Here's some conformation shots of my incredibly ripped horse. I think I'd be happy if she was a little fatter, actually. Thoughts/feelings?
That face. <3 that horse.

Shameful dirty.

Oh my god, Becky, look at her butt. It's so muscular and veiny. Wait, that's not how it goes at all...

I just hope Gold Country has troughs every five miles for me to stick my head in. I do ok if I can stick my head in a trough.
