I attempted 2(R2R2R) FKT on May 22. This is my second attempt. My first attempt was on May 15, which I announced on the FKT comment session. I DNFed in that attempt due to GI issues.


On May 22, I parked my car at the T intersection near South Kaibab Trailhead. I looked for a 2:30 start, but actually started at 2:36.

 I re-supplied from my car, and drink water from water faucets in the park.

I finished the first R2R2R in just under 10 hours, but spent over 30 minutes to run to my car and back, and re-supply and change clothes. The second R2R2R took me about 11 hours. Final time according to my COROS pace 2 is 21:37:40.


I didn’t receive any support from others, didn’t have a pacer, but I met two people who I knew who were also visiting the Grand Canyon. Both decided to join me without I asking, and I didn’t object. One ran with me from near Phantom Ranch to South Kaibab Trailhead during my second crossing, the other walked with me up the latter half of South Kaibab trail during my 4th and final crossing. She also shoot video of me coming to the finish. Neither one pre-arrange our encounter, but were on their own respective Grant Canyon visits
