You only have about 1 week to sign up for the summer challenge. Sure 120 miles seems like a lot, but it's only 1.5 miles 6 days a week. I'm sure most people do that without even thinking about it. As for me, this is a great challenge for the whole family. I plan on doing this on top of my normal exercising. The kids are finally realizing how important it is to mom to exercise. Now, I need to teach them how important it is for them to exercise. The kids will be riding their bikes, scooters, walks, while mom walks/runs to get her miles in. Very doable. Are you interested yet?
