Big Time!!! First time I've ever bonked on the trainer. Had my favorite breakfast of pancakes, threw in the virtual reality ride of Lake Placid and away we go. Four water bottles lined up one with sportsdrink, a homemade powerbar thought I was all set. Well the last 20 minutes I knew I was in trouble but pushed thru it and after 2h55m it was over. I was shot, kept drinking fluids, had a good lunch with all food groups but four hours later I still feel like crap, headache too. I went way over the edge on this one. One thing I learned was my homemade power bar does not provide enough for this intense training video last time I ate granola bars and had no issue. Did burn 2750 calories. Anything you guys promote to help with the bonks!!?? I've never felt like this after a ride on the road but I do focus on my calorie intake a lot more when riding the road.
