So, the concensus seems to be it's all the above. The truth is, I'll often run on coffee & a scone on morning rides and I'll charge that first grade. So, easy enough to prep with some better fuel and pace the effort. Some focused training would be good too, but I've lost enthusiasm about that - too much time and too little incremental improvement. You older guys will know what I mean, like twice as much training effort as a 20 something, and a fraction of the gain. It\'s mostly about delaying the decline.

But, losing weight....that is a win-win..I've got lbs to spare. Darn, wish I hadn't downed those cookies before booting up the cpu.
