On my last Sunday morning ride, I was doing a 50-miler. This was a substantial increase in my mileage, but I rode at a lower intensity level. The first 40 miles or so felt great. By mile 45 I suddenly felt pretty bad. My energy was gone & my legs were getting very tired. Even when I started soft-pedaling, I could not recover. The last 3 miles were the longest miles of my life! Is this what people refer to as a bonk?

Until this episode, I had never put a whole lot of thought into much besides staying hydrated. The night before I had pasta for dinner. On the morning of the ride, I had a bowl of oatmeal. 2/3 of the way through the ride, I had a peanut butter and banana sandwich on whole wheat bread. I drank water. There were no problems besides the sudden loss of energy and light-headedness.

Please critique my riding diet and give recommendations.

Thanks

don't increase your mileage so rapidly. i doubt you get the same sensations on your next 50 miler though... your body just wasn't used to the effort.

From Cycling Performance Tips:

Might have been a bonk (depletion of glycogen) or just doing more than what you've trained for. You want to take in 300 to 400 calories of carbohydrates per hour. Your body burns these calories and stored fat. If you don't eat enough, your body burns stored glycogen. When you run out of glycogen, you bonk.

You bonked. I think the PB&J came too late in the ride for you, and you may have needed more easily digestible carbs. You may also have become dehydrated - weigh yourself after the ride to see if you've lost too much weight.

Old european cycling trick is to drink diluted with water good ole americana coca cola, high test. You get some quick sugar in the liquid form into your system plus a little jolt of caffine, should start feeling better within about 10 minutes. For max results, just drink it straight. I can hear it now, boo hiss, bad nutrition, but it has worked for me numerous times.

As in the songs from Ferris Buellers Day off!

Sure sounds like it. My trick is to drink cordial.
