So.... I used to be a runner, but the doc told me to stop if I couldn't control my heart rate. So, lady year I purchased a road bike and I'm absolutely loving it! 2 weeks ago I bought my wife a Specialized "roll " and our longest ride together was 7 miles and she felt great. I could never get her to run with me, but with her new bike she loves going out. I can click off 20 miles, but mostly because I have a good bike. It's comfortable and fits me well. It's also a Specialized.
