Running Accomplishments:

Pre-high school: I ran a lot of local 5ks and a few half marathons.  I didn't do a ton of training, but I just had fun, and I got more serious about it as high school got closer.

High school: I enjoyed running a lot, especially cross country.  I originally did track to keep my in shape for cross country.  I ran at Footlocker Nationals, the Adidas Dream mile, Brooks PR Invitational, world xc junior championships, and a few local 5ks.

Long-Term Running Goals:

Make sure I have fun, not get burned out, and get faster.

School records in the 5km and 10km.  


Served a mission for The Church of Jesus Christ of Latter-Day Saints from July 2015-July 2017.  I gained 30 lbs. during the service and came back out of shape; however I knew that if the Lord wanted me to once again run competitively, he would bless me to return to fitness. 

I graduated from Sky View High School in Smithfield, Utah. I currently run for Brigham Young University in Provo, Utah.

AM-10 miles. Happy new year!  As I have done for the last 6 or 7 years, I enjoyed a great night sleep last night, choosing now to stay up late. 

PM-5 miles.  

Total Distance

AM-18.1 miles at 5:51 pace with Spencer Nelson.  We did a 5 mile pickup at around 5:10-15 average.  I can't really remember.

AM-12 miles from my apartment. 

PM-6.5 miles with Clayson and Will.

AM-4.4 mile warm up, 5 miles at 24:47, and just over a 3 mile cool down.  Tempo today.  So, my watch battery died, and I left my charger in Smithfield, so I just went with the guys for the first few.  They told me we hit 5:00 for the first mile, which I would've been fine with at the slowest, but it was really 5:08.  After that, I sped up.  Honestly, there's a lot this time can work on, and one of the things I think is tempo runs.

AM-10.3 with Doc.  

PM-5 miles with Clayton.  

Total Distance

AM-12.5 miles total.  4.25 warm up, 2x(mile, 1200, 800) with equal recovery at K park.  It was pretty slick.  Splits were approximate because it wasn't wheeled and my watch's battery is still dead.  I just went off feel, but because it was slippery, it was pretty slow.  5:00, 3:40, 2:18, 4:45 (sun started coming out), 3:34, and 2:20.  Ran on my own for all the reps until the last 800. 

PM-5.7 miles.

AM-18 mile long run in Springfield and up hobble creek canyon.  It was pretty, but also fairly icy at some places.  I only fell once, and luckily I landed in the snow. 

Total Distance

AM-6.16 miles at the track field.  Lots of grass loops. 

PM-13.5 with Clayson, Matt, and Adam.  Matt just informed us he is getting married on Saturday instead of in Februrary.  

Total Distance

AM-5.2 easy miles of grass loops. 

PM-Michigan today. Splits were 4:22, 4:56(grass), 3:15, 4:50(grass), 2:05, 4:50(grass), 59, 4:44(grass).  Felt great on the track for the first few, but after that I knew I had gone out too quick.  Grass didn't feel as tempo-like as it should, which probably means I went too hard on the track. 

Total Distance

AM-7.2 easy miles with Michael and Clayson.  We talked about what Michael should name his daughter.  

PM-8.7 miles with Elijah.  Strides were added on at the end to get used to the indoor track. 

Total Distance

AM-5.2 with Clayson and a friend whose dad served as a missionary companion with Coach Eyestone. 

PM-9.2.  Did an 800, 400, 400, 200, 200 at 2:07, 61, 60, 27, 27, with 400, jog after everything other than the 200s which had a 200m jog.  I was not having a great day with pacing, and ran everything a bit too quick.  Goals were 2:10, 62, 62, 29, 29.  I felt fine though. 

Total Distance

AM-6.75 miles picking up people throughout.  We started pretty slow, and someone passing us started talking to us.  His name is Zack, he just started running a few months ago and has run a 68 minute half marathon.  After Brady Early, a former teammate, ran into us after we talked about how we were surprised we never saw him on our runs.  

PM-4 miles.  3.2 warm up, then strides, 400m at goal pace (too fast...60... I messed up again), and then 200m at 30.

AM-2.1 mile shakeout. 

PM-Warm up, strides, then we raced.  They put us in positions randomly.  This led to me being on the back line.  Honestly, a four lane track with twenty people is already pretty packed, but the start is the worst.  Kramer let me switch him spots so I could be in the front line.  I was surprisingly more nervous than I've been for a race in a long time, but the nerves settled quickly.  We started, I got out well, Talem paced me for the first 4 laps (5 laps to the mile on our track).  I felt pretty good, but could tell we were slowing after the second lap, so I told him to speed up.  After he dropped, I ran a quick lap(50), and then stayed consistent the rest of the way. My goal was 8:00 to 8:05 if things weren't feeling great, and under 8:00 if I was doing well.  With 800m to go, I saw I needed to run a 2:08 for the last 800m to hit 8:00, so I knew I was on pace.  I didn't speed up that much, but maintained well and finished at 7:58.  Afterward, my throat burned from the air in the facility.  While I do like our facilities, the air can burn your nose and throat sometimes.  Just over a 10 mile cool down after.  The team killed it today, which was really impressive to see.

And additional congratulations on 13:28 win/PR, and today's decisive win in the "lions' den" championship. Was very happy to see you put a 20 second gap on the formidable competition over the last 1 K. Made me think of Moroni 7 "has the day of miracles ceased?" Keep up the good work.
