65 miles today. No bonk. I've got a couple of 15 mile loops from my house. Actually one loop is 15 miles and the other loop is 17.5 miles. I did a loop and took a 10minute break at the house, ate a little and went for another loop. After three loops I had matched my longest ride of 50 miles. At this point my wife got on her bike and rode 15 miles with me, at a much slower pace. I finished the first 50 miles in 4 hours, including breaks. The ride with my wife was much slower; 15 miles in 2 hours. But, thats ok I think she will get faster with more training and a better bike. She is still pedaling a heavy Schwinn, so I am proud of her.
