Hi, I've been mtb'ing for about a month now. My bike is not the greatest, but I am loving it! I am 34, married 16 years and have four kids that we homeschool (ages from 15-7). For about three years I have been running and not making much progress. After biking for this last month, I was able to run at a consistent speed for 30 minutes! I know that sounds kind of wimpy, but I was a wimp. My husband rides with me and hopefully, we can get some good equipment for the whole family to ride with us.
