Contemplating the nature of suffering. When you realize your old easy pace is now hard. This is the path with the gravel surface that should be similar to the marathon. 2 gels with the routine I've been on and the 2nd bottle of water had a Nuun tablet in it. Don't like the taste but getting used to it! Breathing was very hard but hopefully at lower altitude I'll have more oxygen! NIce breakfast with the group afterwards. Enjoying the process although I know there's no way to predict how the marathon will go, which we want to be able to do!
