My Marathon Report

November 1st, 2010 by Amy Gonsalves Leave a reply »

Yesterday I ran my second marathon.  I was lucky to have a friend find me and get me through miles 11-26.2 much speedier than I would have if I were by myself.  I didn’t want to let him down, and he wanted me to set a PR (personal record)!!  I finished the 26.2 miles in 4 hours and 26 minutes.  Not bad!  I completed my first marathon in January in 4:36 so I peeled 10 minutes off my time yesterday.  Yay!

I was lucky twice yesterday.  The blood sugar gods definitely smiled on me.  I’m not sure why, but I went with it.  I was fortunate to know in advance they would be passing out my gu of choice– Accel Gel.  Accel Gel has 20 grams of carbohydrate and 5 grams of protein in each packet.  (And there is a chocolate flavored one I can choke down with less difficulty than the other flavors.)

From my heart rate graph, it looks like I stopped running 14 times over the course of the event.  I know I used one of my early stops to call my husband and complain that I was running too fast!  I used that break to re-start my pace to a slower, “marathon pace” for myself.  (I can run much faster in a 5k run than I can in a 10k run, and can run much faster in a half marathon than I can in a full marathon.)

I checked my blood sugar it looks like 5 times during the 4.5 hour run.  I don’t have a plan for most of this; it’s how I’m feeling each run that will determine when I check and what I do.  When I eat a gu, I take 0.1 or 0.2 units just to have a record of when I ate that I can see quickly with a look at my pump’s status screen.  It helps me from overloading on gu and it helps me to remind myself I may be due for the next one.  I’ve learned from experience that on a long run I do best with a gu after 3.5-4 miles for some reason, and that if I skip the gu due to a high blood sugar I will regret it and have a horrible run: I must stay fueled!

So here’s my rundown, in case you’re curious.  Like I said, I’m absolutely amazed I wasn’t higher than this.  I kept my basals between 33% and 67% of my normal rate beginning an hour before the start of the run. 

4:33 140   0.2    
4:35   27 (oatmeal) 1.3    
6:06 242   0.2    
7:00 START MARATHON   Mile 0 0.5 active insulin units
7:37 accel gel 0.1 Mile 4  
8:06 accel gel 0.2 Mile 6.5  
8:30 159     Mile 8.3  
8:52 191 accel gel 0.3 Mile 10  
9:15 161     Mile 13.3  
10:15 159 accel gel   Mile 18.3  
10:45 131 accel gel   Mile 21  
11:25 FINISH MARATHON   Mile 26.2  
11:40 116 (finish)      
12:25 92 (finish)      

14 stops overall; stop = walking through water break

Most (all) of this comes from years and years of trying to figure out what works for me.  I’m posting it FYI and not as a recommendation.  My recommendation is to learn what works for you through trial, observation, and error. 

Have fun!
