I am preparing for a century in a couple days. I've done a few but it's been awhile. In the past i hardly ever rest during the unsupported century, but wonder if there would be an advantage. I usually stop a couple times to refill water, etc. but i just stop long enough to get water, use restroom, etc. and then head out. Usually, no more than 5 minutes.
I guess, I am always concerned that the legs will tighten up so I don't rest long. But having not rested much during these stops before, I am wondering if there will be any gain by resting for 20-30 minutes somewhere along the ride?
