Halfway Through Fasting

For this year’s 19 day Fast* I am using Zero along with Cronometer and my Coros Pace Watch to keep track of some metrics, specifically sleep, activity, food consumption and ketone levels (along with blood and microbiome). Here is how it has gone, so far:

Avg. Sleep: 6.6 hrs (35% deep/2 min. wake)
Avg. Meditation: 30 min.

Avg. Ketone: 1.4 mmol/L
Avg. Glucose: 4.3 mmol/L
Avg. KGI: 3.07

Avg. Calories: 1542 p/day (62% fat, 16% protein, 22% carbs)
Weight Change: 3lbs.

Active Days: 6 of 10
Bike: 28 mi.
Run: 13 mi. (including a 10K race at the Santa Cruz Half Marathon)
Swim: 14 mi.

The Bahá’í Fast is actually time-restricted feeding without food or water while the sun is up.

My Brother Takes the Bull

Two days ago I retweeted my my brother Ryan talking about the cover he did for Bull Magazine and his interview with Portugal the Man, today it arrived, ergo Twitter is magic. https://amzn.to/2EZGazg

You should take the time to read @eliotpeper’s True Blue, released today as a public art project on the web, incorporating web design, illustration, and story. True Blue exists in a world where your status and ability is judged by the color of your eyes, reminiscent of Gattaca, one of my all-time favorite science fiction films. The story is elevated by beautiful illustrations from Phoebe Morris and Peter Nowell’s incredible art direction and development.

Equally as interesting is Eliot’s post about the project and how they went from idea to story, to illustrations, to a web site. There is innovative work underneath a compelling and thoughtful writing, and after reading the behind-the-scenes post, I read True Blue on multiple devices to appreciate the micro-animations and “Narrative Responsive Design”.

The recounting also reminded me of my own post about how I think of art as a verb, rather than a noun, and how it happens when we create, not as the finished object, which I resurfaced for you.

My First 10K Race!

Santa Cruz Half Marathon

With looming storm clouds at the start and sunshine coming into the finish, I couldn’t be happier with my first 10K race at the Santa Cruz Half Marathon. I finished on a 9:11 pace ~ 18th in the 40-49 age group and 66th overall for men. I ran fasted, with a half of a bottle of HVMN Ketones consumed about 1.5 hours before the event. My pre-race ketone levels were 2.0 mmol and my ketone/glucose index was 2.2, which is pretty solid. I’ll break my fast at sundown with a glorious dinner to celebrate!

Weezer's Black Album

I listened to Weezer’s Black Album on my recovery ride today and I propose a new sub-genre for the album: Rockxploitation. Rivers and Company are almost a meta-rock band — a real world Spinal Tap — referential, sarcastic, self-deprecating, and a really good time. They also recently released a Teal album wherein they cover what feels like every amazing song, from Aha to Black Sabbath and TLC. Few of the covers will blow you away, but it is pretty much the best Kidz Bop ever! While you are in the Weezer mood, you might as well top it off with this Weezer SNL skit featuring Matt Damon and Leslie Jones in a brawl over the best band of all time.

Small Fry

You’ll have to listen to Craig Mod’s (@craigmod) conversation with Lisa Brennan-Jobs (@lisabrennanjobs) to find out why it is ironic that the copy of this meticulously and lovingly crafted book, Small Fry, came into my possession with a grubby cover, complete with yellow stain. https://craigmod.com/onmargins/007/

Taking it to the Beach

Yesterday’s ride was a lot harder than it should have been, everyone but me crashed and we had a hard bonk about mile 30. Thankfully, we all made it home. If you need a bonk-parachute, check out SIS’s Go Gels https://www.scienceinsport.com/us/shop-sis/go-range/go-gels
