Run Rabbit Run 50

No photos, sorry.
This year is the first year for the Run Rabbit 100, but I only ran the 50. I've been injured and getting fat, yet me and the bunny have been dueling and it seems I keep finishing long in the same several minute time-frame.
This year, I hardly trained at all. I used to do 40+ mile solo training runs. This year, nothing longer than a couple dozen miles. I used to break 100 mile in a week a couple times a year. This year I don't know if I broke 40.
Something bad has been brewing in my right foot for the past 11 months. It might be related to falling arches. The pain is at the top of the arch, where the bones are crunching together from arch failure (midtarsal fault or dorsal compression syndrome), I think. Or maybe its a ganglion cyst? Or nerve entrapment? Or gout? Any of the above aggravated by osteoarthritis? I know I have arthritis - it shows up in my x-rays over the past few years.
It's along the tarsometatarsal joint and it started last year when I wasn't running. Running aggravates it, but isn't the exact cause.
So not so much pounding like before.
I've been biking a couple hours or more each week to make up for it.

I wanted to beat my previous PR of 11:23 for Steamboat Run Rabbit Run 50, or RRR50. When I got to Steamboat, I discovered they'd lengthened the course by over half a mile. It's now 51 miles. That's an additional 7 minutes, if you average an 11:20 finish.

I used Vi Fuel for this entire race. Somehow, it seems to enable me to burn my own body fat better than any other fuel. I consumed about 80 calories per hour during the race. Trying to force more made my stomach turn.
I carried two 24oz handheld bottles and no pack. My Vi, salt caps, and everything was in my cargo pockets in my shorts.

It was perfect weather and a perfectly executed plan. As I told a fellow running, I felt appropriately delusional, and was counting on my delusions getting more severe as the race wore on.
I'm not in good cardio fitness, but I have muscle, no brakes, and an ability to run through rocks as if its flat ground. This equates to great downhilling. I was counting on reaching the top of the last steep descent with at least an hour left. I wasn't very fast, but managed 9-minute miles for the last 6.5 miles, which was enough to shave 6 minutes off and set a new PR at 11:17:14.
