I am an avid road cyclist and typically do rides of 80-100 miles with no significant problems.

My sense is that the main difference between a "short" ride of 30-50 miles and a "longer" ride of 80-100 miles is simply pacing a little slower, plus of course better nutrition and hydration.

The question is, how well does that extrapolate to an even longer ride?? My friends and I are looking at doing the Mallorca 312 next April, and it's 187 miles.

My hope is that if I can do 100 miles, I would be able to do 187 as long as I pace it appropriately and eat/drink properly.

Is that overly optimistic?? I am not going to be able to do any rides >100 miles in advance of this event. My goal is not to kill it, but to drop the pace, enjoy the ride, and finish it with a big smile.

Suggestions from experienced long-distance riders are welcomed.
