I recently returned from serving a two year mission for the Church of Jesus Christ of Latter-day Saints in Ghana.  I gained 30 lbs. during the service and came back out of shape. I graduated from Sky View High School in Smithfield, Utah. I currently run for Brigham Young University in Provo, Utah.

PM-Race: So this meet we weren't really taking it too easy training wise, but just to work hard in teh week and then to run with whatever we had left.  I had planned, if Coach didn't say anything, to try and push the pace and make it a quick race.  When disucssing the race plan with Coach, he said that I wasn't allowed to lead atleast until a mile to go, so my plan was to just chill until then and then react to any moves.  Warmed up with Danny and Clayton, had a good start, and then just fit myself in the pack.  The race didn't feel very quick.  We were running about 68-69 seconds per lap, and I just stayed in the middle of the pack.  I wanted to move up, but knew there was no point early on.  At 3k or so, the pacer stepped off.  I stayed in the same place. At 5k we were 14:18, which was slower than I wanted, but I stayed patient.  The pace was all over the place.  I got right behind Clayton after 5k.  It felt very familiar to be right behind him, and I'm used to his pacing, so it felt easy running behind him.  At 8 laps to go, I didn't think we would run my goal time of 28:20, especially after we ran a 70 on lap 17 or 18. When Clayton heard this, he went to the front, and I followed.  When he got up there, he looked around, and then took the lead and pushed the pace.  I went with him, but was being thrown around for a bit by other runners.  After that I just stayed on Clayton's tail.  I wanted to pass him, but wasn't sure if I could continue dropping the pace.  As every lap went on, I felt better and better.  With a lap to go, the announcer said we had a gap on the field, so I looked back.  I then tried to get on Clayton's outside and pass him, but he kept the pace quick, and with about 50m to go, I passed him.  I could tell he wasn't sprinting all out because he never has problems responding in practice and I was right.  He was smiling as if it was a workout. 

Fun race, it was cool to get the win, even if it meant Clayton wasn't kicking hard.  5 mile cool down afterward

Nice job! 39 second improvement? Wow!

Congratulations! 14:00 closing 5000. That sounds like sub-28:00 is a near possibility. Back when you were in high-school I estimated your potential at 10,000 as sub-27:00. This race shows that estimate was not crazy, and with the right approach, you can get it.

From Sasha Pachev on Sat, Apr 06, 2019 at 13:57:00 from

So you averaged 2:43 per K over the last 2K splitting I would guess 2:49, 2:37. That is on pace for 27:10, BTW. Looking at your splits, I see no reason why you could not run 66.5 per lap in a well-paced 10,000 on some nice European stadium that is well-shielded from the wind. That would give you 27:42 already.

Speaking of OTQ, the automatic qualifier in 2016 and 2012 was 28:15, and in 2016 the slowest qualifier they allowed was 28:31, so if you just run like this again inside the qualifying window (which I think will start in May), with high likelihood you will get in.

Another thought - when you become more fit, it takes some time to learn how to cash out on that fitness. This is your first visit into the low-28 territory. So a few more fast races could get you to the point where you are actually running at your true capability.

That's the kind of in depth commentary that I've missed! Good stuff Sasha - I enjoy the analytical approach you bring.

Oh... and good job to you to Conner!
