well, after a couple of months of solid training, it seems that this morning I overdid it a bit. I'm afraid that I have blown my turbo. I felt it go at about 10 miles and I still had 3 miles to go to get back to the house. Let me tell you, there is nothing worse than trying to run when your turbo is blown. I had been taking good care of my turbo, you know, all the routine maintenance and all, but sometimes I guess there is nothing you can do. Turbos are mystery man. Please don't take it for granted if your turbo is good.
