A question for Coach Charles or other experienced marathoners:
How many Gu's do you use for 26.2 miles? I know each person is different, but on my long (longest of my life so far) run today of 14 miles, I had success with one every 4 miles, or about 42 minutes (I am using 9:2 run/walk intervals). That would mean like 6 for the marathon. Is that too much?
I felt good after running, some muscle soreness. Not the usual GI issues I have when I finish a half (nausea, needing to go many times). But I am concerned that too many Gu's can cause problems. Thoughts? Any advice/help is appreciated.
I will say that I really felt today like I can do 26.2 miles. It may not be fast or pretty, but I am relatively certain I can get it done.
In general, look to take one between 40 and 75 minutes. YMMV. So at 42 minutes, you are in the proper range.
Learn to 'like' more than one flavor. What will happen about 4-5 hours into a long endurance event (especially if warner than recent training) is that you will start to hate your go to gel or fuel. What I do is put 2-3 flavors randomly along my fuel belt. Then I pull the next one in line off the belt on the road. This prevents you from selecting only one flavor - that is - you will not grow tired of your favorite flavor. I usually pull from the right and back then the left and back moving forward on both sides. I will put 1-2 of my favorites in the last two loops - giving me that special charge at the end.
Also, look to train with Clif Shot Blocks as an alternative to gels. The race will usually have Clif products at mile 14 and 19. At a 10 minute pacer, you should have blocks at those spots still available. It will give a slightly different texture and flavor. They will also have slightly green bananas near those same spots.
So to answer your question, I will carry around 8-9 (as a 10 minute pacer) in my belt. I will take one as my corral is at the line then about one every 45-55 minutes (my interval and allowing a little time for differing water stop intervals). That will leave 2 - 3 extra in the belt. This allows for a mishandling of a gel, passing one off to another who fumbles, or that little extra bump needed late in the race.
YEs, eating too many too soon with too little water can lead to a nausea/GI issue. But then so can too much PowerAde or pushing a little hard. Training through different brands and flavors will allow you to figure out a GI friendly fueling plan.
Hope this helps.
