Nope, I don't mean "bonk" as in Bonk, the book about sex by Mary Roach, but bonking as in carb depletion. Being that I'm only used to four hour bike rides, I seem to have forgotten that I'll need sufficient energy to fuel my four hour runs, too... the hills are pretty draining. I brought along a Luna bar, but homegirl needs her calories. So, my long run for last weekend was supposed to be something like 23 miles, but once I was out there, after about two hours, I was totally kaput. Four hours and 18.3 was all I could do... the last hours I was dragging along, walking and trotting, total amateur hour. I've got my sister's wedding Oct 23, and Nebraska doesn't have much in the way of hills, so I'm a little nervous about getting the stamina up for the crazy course on Catalina (hey alliteration!) Best stock up on em Gus and get on the mountains when I'm back.
