I've liked the Cgm for running and find the data very useful. I also lug my meter in these shorts- Race Ready- that Jerry tipped me off to,. like 15 pages back. I turn down to 40%ish too.

I'm going to try my CGM again but mine stopped communicating during my marathon on 4/22- not sure what the problem was.If honey stingers work for you, that is a good choice. A marathon is different in that your liver will be out of glycogen after about 20 miles of running so you will need additional carbohydrates- maybe more than you are taking for a half marathon. I did not take enough carbs during my marathon and even though I cut my basal rate by 80% during the marathon, my bg was 48 at finish.

So, I am getting ready to run the Flying Pig half marathon this Sunday. I am very excited!!! Also, I am doing the Chicago Marathon. This will be my first marathon. What are thoughts on CGM's. I had one when I was pregnant, and hated it. It was very painful putting it in(I am very small). I was thinking I could just run with my glucometer. oh, I was reading all these comments about nutrition, and I always turn down my basal rate about 40%. I eat Honey Stingers. They are organic energy chews. I eat about 2 or 3 every 3 miles, and I haven't had a low or high during this training.

Sheri Colberg,PhD author of The Diabetic Athlete recommends that for marathons insulin pump users should reduce basal rates during the marathon by 25 to 100% to minimize circulating levels of insulin. I see no need to take insulin for the carbs consumed during the marathon unless you are getting high blood glucose readings. Working muscles take sugar out of the blood without insulin. Also I think the best drinks or carb sources are ones with glucose and fructose. I don't see any need for additional nutrition except salt unless you are running an ultramarathon. From Dr. Mikrin---http://www.drmirkin.com/public/ezine042212.html
Part of his article-Drinks that contain both glucose and fructose sugars will help you race faster in competitions lasting more than a couple hours. Drinks that contain only maltodextrin, (made from starches extracted from rice, corn, potato and whole grains) are not as effective for racing because maltodextrin contains just the single sugar called glucose. However, drinks that contain maltodextrin plus fructose improve race times better than those that have maltodextrin plus glucose (Applied Physiology, Nutrition, and Metabolism, April 2012).

Thank you Acidrock and Jerry for your input. I will keep you posted as I experiment in the next months!Of course I will have many more questions!!!

I try to take in some carbohydrates every 45 minutes to an hour on long runs, and I set my basal rate to anticipate that.

this seems to be a pretty good article about nutrition?


Comment by acidrock23 on May 2, 2012 at 5:35pm

I agree the longer training runs are more hair-raising, since you have to lug your stuff with you or set yourself up. At the height of marathon "season", Aug/Sept, in Chicago, I'd go ride my bike around the 6 mile loop by my house and see people with backpacks and stuff stashed alongside the trail. I think the "how much" question is something that you have to find out, if a few G of lifesavers works for you, I'd say extrapolate that out will work but I would want something more "foodlike" at the "turn" or 1/2 way point as you get out longer than 2 hours? Hydration is almost as important as glucose as running out of water can get ugly pretty quickly too?

Thank you Jerry! That is exactly what I feel would be the right thing for me too. I would rather be elevated and correct later after the race than go low while running.
Okay, indulge me one more time, as far as the fueling goes how often do you fuel yourself during a marathon...I realize a lot of this is individual but just trying to get some ideas for my up coming longer runs?
