David Goggins challenge.
- Run 4 miles every 4 hours in a total of 48 hours.

This is Tucker Carter for finishing the 4 x 4 x 48 (4 miles every 4 hours for 48 hours). Photo from Facebook.
Tucker, photo shown, started on a Friday afternoon with abnormally warmer weather of 75-degrees F and clear skies. Then came rain and temperature drops the next day to 30-degree weather for the final run in the rain. It was tough mentally and physically. He continued to push thru and persevere. Way to kick butt and put 48 miles in 48 hours behind you!
