Do you carry any gels, or Shot Block type supplements? I believe in a combination of those, and in your case, the schedule of Fig Newtons you set.
No, I don't really know anything about gels other than the fact that they exist. I'll have to look into it. What is their advantage over food?
For me, I think the bonk actually started about 5 hours in, that's not a long time for me to ride. But I didn't take into account how much harder this day was than anything else I've ever done. Even that 7000 ft climb in the Ride Around the Bear wasn't as hard, it was long but not steep so I could just go at my regular effort level which I can do for a very very long time with my normal eating pattern. This climb was steeper, so I had to work much harder. I was burning way more calories than normal, I just didn't recognize it.
It was a good lesson, though, a tough climb like that I need to be 100% aware, not let the nutrition lapse afterwards.
Oh and I'm so sad. I'm afraid it means more training too. I guess I need to ride my bikes more.
