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.

      Great day to run.  Or atleast that is how it seemed when I went outside where I was staying that morning.  It felt really warm for a morning.  About 60 degrees.  Then we got to the starting line and I changed my mind.  Then was a pretty bad head wind.  Did some stretches, warm ups, waited for the race to start with Claire.  I went to the start line, and saw that there were 2 guys in BYU jerseys.  I recognized one from the St. Georgre Marathon, he ran for BYU in the 90's I found later found out, and the other was also a graduated BYU runner.  So when the race starts, me and 5 other guys are in a lead pack.  I wouldn't regularly be running with these guys, but with the big headwind, I needed people that would push me and that I could draft off of.  For the first two miles I felt alright, and stayed with the lead 2 guys, the younger BYU guy and some other guy, with a tall guy behind me.  After the water station at mile 2, they left me.  Then the taller guy passed me at that same mile.  He was about 10 yards or so ahead of me for the next 2 or 3 miles.

      Those next few miles were terrible.  Running by myself was harder than ever.  At maybe mile 5 or something, the older BYU guy and another guy who looked really familiar (I later found out it was Braden Perry) passed me and I drafted off them for the rest of that mile, During which we caught to the tall guy.  We had averaged a 5:20 mile for these miles until about mile 9.  I  lost these guys at mile 9, where Braden hit the porta potties, and I felt like dying.  I never saw Braden again until the finish, but he said he hit them a few times after that.  By then we were out of where the wind was.  They were only about .05 miles away at mile 10, but kept gaining time on me.  During this time, I was on a pace to be in the 1:10s, and I wanted it sooo bad, but I didn't have all the energy in the tank to pull the right pace.  I tried sprinting, but couldn't at the end.  I finished, and stopped where the first chip time things were.  This was a big mistake, because I stopped my watch at a 1:11:00, and just tried to keep myself up, while the real finish was about 10 feet beyond where I stopped for those terrible time consuming moments.  I walked for it and thought I had a 1:10:59, due to chip timing, but later I found out I had a 1:11:24.  Bummer I guess, but that just means I know I can get a PR next time.  Later I saw a bunch more people I knew especially people from Fast Running Blog.  Later got a check for $75, but couldn't accept it for some high school rules about running or something like that.  Fun race though.  I saw the marathoners finish, and that was a harder race than usual.  Most times were 15-17 minutes slower due to the wind.  It was surprising to see the winning kenyans with times in the 2:30s

Geeze, you did well in those conditions. I saw you and you looked like you were booking it! Rules smooles. Blah!

Hey Conner, great race! That $75.00 has a lot more to do with NCAA eligibility down the road than any high school rules.

One of my super Alta runners, Whitney Paskins, is now on the blog. She'll be a soph next year like yourself and was the 5A state 3200 champ. maybe you could comment on her blog sometime? I know there aren't too many high school runners.

Great race. Keep working hard and your going to have a lot of other great races down the road.

Great run Conner - 2 minutes faster than last year is a great improvement, especially considering the wind. You continue to impress!

That wind...Let's shoot for a 1:10 together at TOU half.

Conner, great race. You are running times and paces well beyond your years. You are going to be a strong and fast runner! I'm excited to track your progress.

This was probably worth 1:08:30 - 1:09:00 without the wind.

You can solve the crash problem by upping the mileage. At your age you need to be cautious so as not to stunt the growth, but I think 50 miles a week should be quite safe. Easy pace, anything 8:30 per mile or faster is fast enough. Sub-7:00 is probably too fast. With the increased aerobic base you will be able to hold a greater portion of your speed. Next year you might be able to crack 1:05 if the conditions are good. This estimate is based on expected improvement in speed from the maturation + improved aerobic fitness from increased mileage. Higher mileage does quite a bit of a wonder in allowing you to race any distance up to the marathon at a very high percentage of your 2 mile speed.
