Depending on how carb adapted you are, a few days is not enough. It could take weeks.
Plus, the clif bar just told your body that carbs would be the fuel source du jour and since you had very little, it totally hosed your body up.
If my 40 year old ass can play a full LAX game as a mid-fielder with nary a carb in my system, then your punk ass should be able to ride a bike for 6 days non-stop once you are fat adapted. That last statement has no scientific backing, but you get the point.
Just keep on with the Primal eating (at least 80/20) and you will become fat adapted in a few weeks probably. It may take a little longer or a little less time. And quit eating candy bars (aka "energy", "cliff", etc.) all the damned time. Just sayin.
And while I am not a cyclist, I know a shitload of them. My wife works for USA Cycling and I go to a lot of the events and stuff. Most are skinny enough to tread water in a test tube, except the mountain bikers.

People too weak to follow their own dreams will always try to discourage others.
