Goggins 4x4x48 challenge

David Goggins author of "Can't hurt me" is definitely a mentally tough person. As he has proved on many occasions. He came up with a challenge to run 4miles every 4 hours for 48 hours.

The 2022 challenge is due to take place on the 4th March 2022, due to my work schedule this was not possible for me. 

I started my challenge at 8pm on the 19th February 2022 as I had booked a couple of days off work. 

In true Duluth 2022 winter fashion we got a snow storm and cooler temperatures during the 48 hours I ran. 

How did it go?

Pretty well actually, I had not really planned on doing this until about a week before I started it. 

I knew it was going to be more running than I'm used to doing at the moment so I planned on running at around 9:30min/mile to 10:15min/mile as this should be a pace I could maintain.

		Total	48.59

Mostly I ran on the roads with the exception of run 6 on Sunday which was partly on trails. 

All runs started and finished at my house and were on pretty flat courses. Runs 2,3,8 and 9 were a double 2 mile loop. 

It started snowing on run 10 so the last three were on "plowed" streets closer to home and as out and back runs trying to take advantage of the clearer streets and avoid traffic. 

Running in the sun for run five.

Heading out for run 12. 

Thankful for my wife clearing me a path to the street
for run 12.

"Plowed" road about 2" deep in snow.

Final thoughts

It was a tough challenge, by the end I was tired! If (ok when) I do it again I would like to start the challenge better rested. Having routes planned ahead of the event helped me. Listening to music or audio book was good though I should have probably charged my headphones before the last run. 

The midnight run was harder than the 4am run for me. 

I was very thankful for my family support throughout this event, I would have struggled without their help.
