I had the same initial thought as you- not enough calories, but when I added it up, 90/gel, 300 for a half cup of dates/walnuts half and half, she's at 390cal/hour. That's almost the limit of what a very good system can process. Plus the walnuts are giving her plenty of protein/fat. It's gotta be something else- wind, hills, speed, undertrained. I'd like to hear what happens next time at that distance. I went thrrough a phase as I was building from aobut 40 miles to 70 or 80 miles where every time I increased, the last five miles would be awful. Then the next time I did that distance, fine. Now I can increase without that happening.
