Race Report: USMS 10K Postal Championship

by Evan Morrison. 04 September 2010.

Another Friday, another long postal swim at the UIC Natatorium. This time, for 10K: 200 laps of a 50-meter pool.

The open-water 25K.

I was joined by fellow distance freak Smelts and my favorite U-Chicago professor were also on deck, as lap counters - which I’m told on good authority is a similarly mind-numbing experience.

My goal? 2:17:52 - my open-water 10K time from Noblesville in July.

Some reasons I might succeed in beating that time:

Some reasons I might not succeed:

What else can I say? My splits will tell a better story than my words:



(1) 5K Postal splits (dotted blue line) superimposed for comparison.

(2) Drink breaks at 2/3.5/5/6.5/8K are “adjusted out.” See 5K postal report for a description of the methodology._

Remarkably, these splits correspond fairly well with my subjective experience:

In the end: 2:16:15. Pace per 100m of 1:21.8. A few more stats:

400m splits:

1000m splits:

5K splits - breaks included (no adjustment):

Nutrition & Hydration:

(HEED = “high-energy electrolyte drink” - e.g., Gatorade)

(recovery drink = includes protein/amino acids - e.g., chocolate milk, GU Brew)

And speaking of recovery: one week ‘til Big Shoulders!

Forward, march!

Good swim, man. For what it's worth, I recovered much more quickly after the pool 10k than the open water 10k. Though the wheels fell off right at 8k again. The large pile of food I ate 30 minutes later helped.

"...wheels coming off..." That's so funny to those of us happy to maintain 1:31/100 for 300m!!! And my wife agrees. Lap counting is a mind-numbing experience. And all she's had to count for me is the Brute Squad (which for me, took forever!). Great swim. Hope to do the same (distance, not time) in a couple years when I get back to the land of normal pools. Oh, and what sort of gel do you use?

Thanks, Adam. Large piles of food certainly help in these situations. Now, don't be shy :-) How'd your swims go?

Thanks, Mike. I hadn't heard of Brute Squad 'til I read about it on your blog. Sounds like a blast. I have a halfway decent 400 IM if I train for it, but during open-water season my non-freestyle strokes go out to pasture. 200 fly, on the other hand, I've never cared for. I've had good results with both GU and Hammer gels. I think I slightly prefer the taste of Hammer. The GU Roctane gels are great but too expensive.
