Follow up on Feb. 12th Half Marathon: Lessons Learned and Next Steps

Posted in Lessons Learned, Nutrition, Paleo Athlete, Training with tags on February 13, 2012 by Living Against the Grain

Today’s race was amazing. My finishing time wasn’t fantastic but the atmosphere was great, and the course was beautiful. It was rainy, but not too cold and the other competitors out there brought a great energy to the event.

I came across the finishing line in 1:26:08, a new PR in the half marathon by over 3 minutes, but admittedly, slower than I had set the cruise control for.

The goal time of 1:22 was a stretch but I really wanted to experiment with it.

Race strategy was two pronged:
1. Set a pace equivalent to 95% of my 10k PR and hammer it out for as long as I could until I couldn’t hold any longer.
– Reason: Test early season fitness identify weaknesses: Strength, speed,
mechanics, etc.
– Key take aways: Monitor when and where the pace became unsustainable and why.

2. – Drink only water and eat nothing
– Reason: Test body’s ability to metabolize fat during the race once glycogen stores had been depleted.
– Key take aways: Monitor when and where the shift from glycogen to fat occurred and test the efficiency of metabolizing
fat for energy.

Obviously you shouldn’t run two pronged experiment like this if its your A race of the season. By then, you should have everything figured out and dialled in. But today was a perfect opportunity.

I believe that self experimentation is a very important element to an athlete’s training plan. If you stay in your comfort zone, or always take down the same gels or sports drink its hard to see where your limiting factor is. Pushing out of your comfort zone allows you to see where your mechanics, strength, endurance or nutrition plan fails so sometimes, your best strategy is to just go for it and see what happens.

So I set my pace at roughly 3:50/km, fired up my POSE running technique, drank a little water at each aid station and stuck to my race plan.

Things were going well and I felt great for the first 15 km. I was right on pace, cruising along the Stanley Park sea wall and feeling fine. But the last 5-6 Km were a little slower than I had hoped.

Deciding to race without any high Glycemic Index gels or sports drinks may seem foolish to some, but my goal was to clearly indicate the point in the race in which my glycogen started to run out. I then wanted to gauge my body’s ability to efficiently metabolize fat for energy.

Why just read about this stuff in text books? I believe there’s some inherent value in going out and experimenting yourself!

To summarize my findings from today’s race: Things were cool and smooth until 15km.

– I average 3:49/km for this portion of the race and my energy levels were stable.

From Km 15-21 I was struggling to keep pace and my energy level dropped.

– I averaged only 4:05/km from KM 15 on.

The data I gathered today will now allow me to go back to the drawing board for my next 4-6 week training block.

– More stamina work, more strength work, and most importantly, GETTING THIS PALEO RACE DAY NUTRITION FIGURED OUT!

I think I’ll be experimenting with some of the stuff on this interesting blog post I just read:

If you have any insight for race day nutrition, please post in comments. Thanks!
